One of the better "slide rule dial" general coverage receivers  Time owned: more than 12 months
I bought one new for my grandfather in the 70's and had one of my own that I brought back from the dead a few years after that. (The earlier production units did not have clamping diodes across the antenna terminals and mine needed the RF amp mosfet replaced.)

Electronics Illustrated magazine did a thorough review of the Allied A-2515, Lafayette HA-600, and Realistic (Radio Shack) DX-160 back around 1968. All 3 are solid state, slide rule dial, GC receivers with ham band (80-10m) bandspreads. All had an RF amp stage with preselector (antenna trimmer cap). The Allied and Lafayette retailed for $99.95, whilst the Realistic was $129.95. Each had a matching external speaker (no internal one was included) that retailed for an additional ten bucks. E-I Mag's findings are still valid today in 2018...

The Realistic had the best stability, comparable to the Hammarlunds, but without the big cost or the vacuum tubes. It's sensitivity was midrange.
It's s-meter was very accurate. Bandwidth was wide for shortwave use, but quite usable for SSB/CW if the ham bands weren't packed with signals.

The Lafayette was very sensitive, but it's s-meter was very "generous". Bandwidth was the widest of the 3.

The Allied A-2515 was very narrow banded. Sensitivity was just below that of the Lafayette, and comparable to that of the DX-160. This made it great for ham radio use, but the IF filter clipped the sidebands of standard MW AM radio stations, causing the muffled sound about which other posts have complained. If you spun the tuning dial through the AM broadcast band, you'd hear the stations "chuffing by", much like that of a synthesized portable radio. Shortwave AM audio was passable. SSB/CW reception was the best of the 3 radios. 1970 would you really buy a radio like this to listen to your local AM radio stations? A six transistor AM pocket radio should be used for that !!!

Slide rule dial radios like these 3 normally have lousy dial calibration. All three of these rather good radios for their time had a band "D" that covered about 10-30MHz, including 20m, 15m, CB, and 10m. Once you found the correct spot for the main tuning, the ham band bandspread was fairly accurate. How do you get to this sweet spot? Heathkit sold a gaggle of HD-20 100KHz calibrators to make this possible !!!

As a bonus, all 3 of these radios, unlike the Hammarlunds, cheapie 4 or 5 tube SWL receivers, and even the more expensive Nationals and some Collins-es also did a fine job of covering the beacons on the 153-500KHz longwave bands. On a good night from the east coast of the USA one might even hear the megawatt LW stations in Europe. (Not bad for a hundred buck radio in 1970.)

I really liked my A-2515. Several years before my grandfather died, my aunt and uncle bought his A-2515 and speaker for about $50. (He upgraded to a Yaesu FRG-7 on my recommendations.) Lots of good SWL time, however, was enjoyed with this receiver by them and me. Mine was horse traded to get better ham equipment way back when I was a starving college student.

These 3 radios were quite an accomplishment for their time...way better than the Hallcrafter S-120's or Heath GR-64 like I had built in 1970. The sunspots needed to be at their peak to hear anything above 10MHz on those 4 or 5 tube radios without an RF stage...other than images or birdies.

Just don't expect any of these to hold a candle to a Kenwood R-1000, Yaesu FRG-7, or similar. Technology marched on and made even better mousetraps in GC-SWL receivers in the years to follow.

Avoid   Time owned: 0 to 3 months
At times items in eham reviews receive a fairly good rating. So, I bought this Allied A-2515 receiver based upon the other reviews.

I owned a lot of receivers over the last 50 years. This Allied is about as poor as it gets. Even after an alignment- bad news.

The audio is very poor (muffled) and using an external quality speaker does not help. Stability is awful. Dial calibration is not near accurate from one end of dial to the other.

I would prefer a Hallicrafters S-120 over this Allied A-2515. As poor as the S-120 receiver is (see other reviews), at least the audio is clear.

Got a "sort of" working one in nice cosmetic shape for $25.

Noisy controls, dial calibration WAAAAY off, but it rcvs SSB OK and seems surprisingly stable. Has 3 IF stages and what looks like a product detector for SSB. AM seems distorted, but that could be some bad caps

I am going to clean the controls and give it an alignment. I'll test a few electrolytics and see if a wholesale recaping is justified.

I looked at the power supply regulator schematic and it is pretty basic, just some caps and a zener diode on the output from the rectifier diodes. Audio is push pull from a center tapped xfmr T-1.

One nice extra is beacon band reception form 150-400 KHz on band A.

The BFO osc seemed really solid and stable. The schematic shows a very simple one transistor (Q104) BFO osc using a variable cap for tuning.

Except for the IF xfmr slugs all other alignment adjectments can be made from the bottom panel (no removal needed) on a neatly designed strip of slug tuned coils.

This is a re-labled Lafayette rcvr and may have been designed by Trio. Runs on 120 VAC or 12 VDC. Has provisions for rcvr muting when used with an xmtr.

For $25 how can I complain? I can't. It surprises me to see that these have sold fairly recently for above $150.

It looks and weighs in like a tube set but it's all transistor.

Front end has FETS (Q401 and 402). Good design with diode clamps on antenna input to prevent blowouts. I wish Sony had been as careful on the 2010.

The more I look at the schmeatic the more respect I have for the design this baby. Mine was built around 1971 and its still working 40 years later. That does tell you something.

Very easy to work on.

Great For Casual SWL'ing  Time owned: 0 to 3 months
The A-2515 has the "cool factor". It's a very nice looking radio.

It's great for casual SWL. Don't expect too much above 20 MHz, but that's the norm for any hobby grade radio, anyhow.

If you're expecting it to be equivalent to modern equipment, don't bother. On the other hand, don't hesitate to get one. The babes dig 'em! :)

Sorry if I was too technical!

Unique, great beginner radio  Time owned: 0 to 3 months
Long post..............sorry.

I was torn about what to rate this radio. Regular readers of the 'review' section, will recognize my call and my 'love affair' with low - end boatanchor receivers.

I had seen this model in Fred Osterman's awesome book: "Shortwave Receivers, Past and Present". I wish Fred would do more books like this. I consider it the 'bible' here. Why? Because his ratings almost always mirror my own experiences....

Anyway, this radio looked like a re-branded Trio (Lafayette), but was sold by Allied and was solid state.
I found an absolutly perfect example on ePay, er, eBay, and it was mine for cheap. Heavily bid, but I won....

When I got the radio, I was amazed at the condition, It had been well cared for. Other than a light coating of dust on the inside, it was just like new. The controls were very stiff indicating it sat unused for a loooong time. After verifying it worked, I replaced the line cord with a 3 connector version, as I do to every piece of vintage equipment that come in here.

I carefully disassembled the radio for cleaning and to respray the covers. I found an off the shelf 'rattle can' that was the EXACT color! Lucky!
Anyway, I removed the dial glass, and I was VERY careful atound the dial markings. I recently destroyed the VERY fragile dial markings on a nice Lafayette HA-63. I had to 'Digital Dial' that radio and have since bought another, out of frustration. All the old Lafayette radios in my collection have that one bad trait... The dial markings were a water emulsion and if touched (however gently), they dissapear like magic!!!
I was pleasently (VERY) surprised to discover the A-2515 had PAINTED dial markings! Now, you can Windex BOTH sides of the dial glass, and really make it sparkle.
Internally, I expected to find the circuit boards marked with "GRE", the Allied vendor back in the AX-190 / SX-190 era. They were different. However, the knobs and dial glass are obviously made by the same vendor Trio used.

How does it perform? Wonderful! It is one of the few old radios I have restored that I did NOT have the desire to do an alignment (yet). Although it is quite easy to do, since the radio came with the Original Manual with alignment instructions.

I have found that the capacitors in these older radios lacking. Just this week, I replaced all the electrolytics in my AX-190 due to power supply hum....

I was very fortunate in that nobody had 'golden screwdrivered' the slugs in this radio. They are all untouched. I have an Allied SX-190 that is now a 'parts radio', because someone broke EVERY slug , on EVERY board! Groan!!!!

After getting her back together, I have it playing on 15 MHz WWV and it is loud and clear.
The only negative thing I can say about this unusual radio, is that the tuning is very sensitive. It's best to tune above your target frequency, then 'tune down' using the bandspread.
This radio ia excellent and just like my FRG-7, I can look inside and ask myself "how the @#$%^& can this 'empty' radio work SO well?".

All I can say is if you run across a nice example like I did, buy it. You won't be disappointed!
