Excellent service Time Owned: more than 12 months.
Purchased a SB220 a few years back. Purchased a number of Harback upgrades for it: meter board, capacitors, fan, soft start, soft key, etc.The kits are excellent, but there is better news.

For reasons unrelated to the amp of the kit, I have been unable to complete / integrate the upgrades then, got distracted by other things like work and house.

I recently started working on the amp, and unfortunately found that one screw of one of the capacitors had damaged threads. This is a problem - I'm in the Netherlands, we use metric, not imperial screws.

The amp was also missing hardware for the interlock, which I wanted to restore during the renovation.

I sent mail, and Jeff responded immediately and sent replacement screws and the other hardware I did not find. No charge, and that includes no charge for shipping to the Netherlands.

His service is second to none. Highly recommended. Thanks Jeff!

Excellent Product Time Owned: 6 to 12 months.
Bought this L4B amp from the original owner who passed away and his son just sold it to me. The amp was seated on a shelf for quite some time and even though was fully operative the PS was running quite hot after several months of use. So, taken into consideration that the amp has never been serviced and it was around forty something years old I decided to replace the caps along with the diodes and resistors.
I got the replacement kit from Harbach Electronics, since is the best deal for your money and pretty straight forward mod.
It took me about two hours to assemble everything and install it. Components are top notch and really easy to follow the instructions step by step.
Now my amp's PS runs way much cooler and I can rest assured that the amp is going to run several more years.
I really recommend this conversion kit to all of those that are looking for a top of the line components with an unbeatable price range.

Excellent Time Owned: 0 to 3 months.
Just finished installing the soft start, soft key, and HV power supply kits in my half a century old L4B. Everything fit, quality great, instructions were clear, and when I left a voicemail asking a question got a call from Jeff in an hour.

And everything worked first time.

Can't do any better than that!

great kit and support Time Owned: 0 to 3 months.
1978 SB220 I built now has the fan,rectifier/meter board, capacitor kit, and soft start kit. Great quality components and detailed instructions. The parts are in kit form and although they are not heath kit style assembly(guiding you hand in hand)still with basic electronics knowledge you can assemble them. I had one issue with no cathode bias when everything was buttoned up, but just resoldered the rectifier board again and replace the B- wire with a heavier one and it came up.As far as support I had checked an sb200 fan on my order form by mistake (everything else was sb220, and Jeff called me to verify which fan I wanted, since he saw the other components were sb220.That's nice service!!!

Great upgades and replacements Time Owned: more than 12 months.
I have used all of Jeff's upgrades and other parts for my Drake L-4B Amp. I have installed the SK-401 Soft Key Module. I have installed the SS-400A Soft Start Module. Most recently I have rebuilt the power supply with Jeff's PM-400A Replacement Power Supply Module. During the rebuild I replaced all the other parts that I could replace while I had it down that far.

Jeff's instructions on all the kits were very clear and descriptive. All the Kits installed with ease and no problems.

If you need parts for your Drake L-4B Amp give Jeff a call!!!

Highly recommended!!!!

Hand Grenade disposal Time Owned: 0 to 3 months.

Jeff saved my life, I bought the PS board for the L4B which was easy as pie to do and a quality product. The board went together real easy and upon removing my old cap/diode boards I happened upon two axials ready to detonate in my L4B. I had to call the bomb squad to remove those from my house. Jeff's products are awesome and he just may save you from a face full of aluminum and paper and a whole lotta smoke.. The Drake works superb with his kit and the PS is much cooler and quieter.

Excellent! Time Owned: more than 12 months.
Jeff is a friendly guy with indispensible products. They are inexpensive, high in quality, install easily and the instructions are clear and complete. I bought an SB221, it was stock from 1978 in exceptional condition. Those few areas that had become compromised due to sheer age were all addressed by Jeff's mods. My unit had a soft start already, I added soft key, filter capacitors, and a new meter board. When you hit the thunder switch (power ON) you dont wonder what old 30 year old part(s) are about to take a hit. I also bought some spare parts from Jeff that were not installed, it is handy to keep a new relay and circuit breaker on hand for the future since he has them. About all I did not get from Jeff was a new front panel and knobs, which are available elsewhere.

Superb Quality Time Owned: 0 to 3 months.
I am very happy that I installed the Harbach mods to my SB-200. The original boards are primitive by comparison, and the new components are of the highest quality. Prices are reasonable, considering the forethought which went into engineering these kits. A little hard to reach on the phone, but both my internet orders were filled and shipped immediately. Very honest dealer, won't sell you something you don't need. Instructions were clear and simple. I wish everything sold to the hobby was this straightforward.
