Some of you guys have no idea how arrogant some of your comments would sound to people in other countries. In some places a hard working honest Ham may save up 2-3 years just to own an amp like this, he may have to use a weeks pay to ship it to me and you guys just think he's going to accept an argument that it's not a Ham Amp Shocked That's why I said at the start that I am not calling him to tell him this stuff, it's easy to say it on a forum but I would love to hear some of you say it to the actual owner in person Wink.
Then he should have saved up for a couple more years and bought a decent amplifier. The shipping alone to another country can be more than what the amplifier would cost if bought used. Overseas hipping is painfully
expensive! I would not be surprised to find that it came from Central or South America.
I don't think any one knowing about this or other CB amplifiers would worry about telling him face to face what the amplifier is about. The truth hurts but it can also be easily demonstrated, explained. False claims cannot.
The 5300A has claims of 500 watts output with 10 watts drive. A perfect drive level for a SSB CB radio. Not much use to 95% of the HF ham rigs out there. Go figure!
Some of these CB amplifiers will have undocumented component changes that can make them difficult to repair. Even Dentron who made genuine ham amplifiers did that a lot.
It is unfortunate that so many newer hams are spending good money on these amplifiers to find they do not perform even close to what was expected. A LOT of these amps were sold so a LOT of them are out there still.
I've seen more than one CB amplifier with a "bandswitch". There was a 49¢ single-wafer switch installed, with NO wiring attached to it. The front panel was labeled 80-40-20-15-10; the switch was labeled "BAND".
But the amplifier had a bandswitch, so it must have been okay, right?
Yeah, no kiddin'!
And the ones titled as CW transmitters too.
RF Parts according to the web page said they have stock on the PT9847.
The listed price is $32.00.
It may need all four replaced. If so, it's kind of a pricey repair for what it is.
Then there is the matter of regulations in whatever country this amp is to be used, which may not be very much like our FCC regs at all.
Possibly but that would not change that it's spectral purity is very poor due to it's design.
In any event it will be a learning (and maybe expensive) experience for at least one ham, and likely two.
