Morning Jim

I don't knew how you asked about to get the ACOM schematic. Did you ask the dealer in US or direct to ACOM in Bulgaria? I have an ACOM 1000 and an ACOM 1010 and I asked the dealer in Sweden to get the schematic. But he refused to give me the files. So I sent a request direct to Val at ACOM Bulgaria with the s/n of the Amps in the e-mail. And after a few days two CD's drooped down in my mailbox with all the files and schematict and service instructions. So try this.

I used the following e-mail

Best regards

I had an ACOM 1010 for a while that I bought used to use for CQP county
expeditions. It was fine to use, but IMD was a bit higher than my Titan
425 and my KPA500, so I eventually sold it. I was also put off by the
fact that ACOM WILL NOT PROVIDE A SCHEMATIC. Not a bad amp though, very
user friendly, easy to tune. The original owner sold it to buy a KPA500
to get 6M (the 1010 is 160-10, 500-600W).

The ACOM 1000 is essentially the same amp, same tube, but bigger power
supply so can run more power. It also covers 6M, which is a big plus if
you operate that band.

##  No schematics, WTF? Bye bye Acom.  I should as heck wouldnt buy one.
However, the schematic is online from various google sources, esp in the UK. ..which has the complete manual + schematics
+ board layouts.

## The pair of 3-500Zs in the AL-82 for a 160-10m will work nicely...and has way better IMD than any GU-74B. IF you were hell bent for 6m, that is another matter. Adding QSK to the AL-82 is not an issue. Eimac never did make any tube called a 4CX-800, that’s just creative nonsense on the part of Svetlana....selling their surplus military GU-74Bs..which
have been out of production for eons.

## Nothing to blow up on a 3-500Z amp. Most have zero grid protection. If you want grid protection, just install a rear apron mounted 3AGC fuse holder, and use a FAST 200-250 ma rate fuse. Wire the 3AGC fuse holder between chassis and positive of grid meter.... or positive of the grid shunt. High swr protection can easily be incorporated into the wattmeter, like whats
in the array solutions  power master series of watt meters.

## The Acom 1000 is a 1 kw output amp. and it wont put out 1 kw rtty /fm from more than 2-3 mins per the manual. The acom 1000 only weighs 18 kg, which is pretty light weight = 39.6 lbs.

## the AL-82 weighs 76 lbs..and will do 1.5 kw rtty. Simple amp to both operate and repair. Parts
are easy to find..and readily available from  Ameritron and else where.
