I gave up on my other modulator because I couldn't find another tuner pot for it. The seller says the little light in the left lower corner doesn't work and he doesn't even know what it's for. Do any of you know what's it's for?
Thanks guys, Wayne.

I cant get a peak on the tune knob, it is fully UN-meshed.
I tried to retap the coil but it only drops the power down, the TUNE peak is still at full mesh.

What do I do?

Please help I dont wanna hurt my amp!

Based on the reputation of these amps, I wasn't expecting much but when I looked around for the specs I was a little surprised to find out what it is for the price. It has complete band pass filtering for each band, SWR protection, and achieves 500 watts on SSB with about 20 watts drive.

They're about $400 and you can find them on ebay and other sites. If anybody picks one of these up, let us know what you think.

Here is a link with some good pictures and other details

Does a new Palomar Elite 225 have two big 5 watt resistors in them, right next to each other, when removed or disconnected, allow 10 meter operation?

This is from another thread I started yesterday in the Tech forum. Friend brought the amp by and show me the "loose" parts he saw and thought they were diodes. They appear intentionally unsoldered (1 leg) and left in place. The board area around the resistors does not look discolored from any overheating nor are any other nearby components affected.

He was looking around inside because the amp is recently doing around 20 watts or so less than it has been and he was just fishing for problems.

So I don't think anything is wrong, maybe the pills are just beginning to get slightly weaker with age. Amp otherwise still works good and sounds clean and clear.

So does this amp require a 10 meter mod via two resistors?

I need some help With an amp I got in a trade deal. It is a D&A Maverick Dual Power 4 band amp. Cant find any info on the web, only the grey Maverick 250. This is a tan front with a brown case like the bigger amps, and has a switch for 10, 15, 20 and 40 meters. It is an 8 tuber, with 4 6JT6a's driving 4 6LQ6's. Can it actuually be used on those bands or is it strictly a 11 meter amp? Drive? Output?
Any info would be appreciated.

Thanks in advance.

Ok I had this forsale 2 times I wanted to sell and buy another amateur amplifier or trade it for one or an HF rig and had no luck other than a hit I had on another site that was a scam I caught early and the P.O.S. ran when I caught onto what he was doing. Anyways I was thinking I might aswell use the thing now instead of leaving it sit in the closet.

3 X 50 Amp supply setup should be fine after volages are matched. :) some of you have been a huge help with info on this for me and I appreciate it. I know this is more of a pain to setup and an straight AC setup is more practical or easier to do but as I said Im not gonna let this 1600 sit anymore its a waste of $$ to do so.

Now what gauge wire would you reccomend for connections I know theres 8 guage comming out of the amplifier but should I then go into 6 or 4 gauge at this point and inbetween power supplies? I also think I will hunt for another legal limit antenna tuner for this setup.

What has actually been seen come out of one of these 1600 for output power AM/FM SSB/CW?? Im going to start this within the next 2 weeks I think if its not ssold by then this is what I am working with and have any of you seen a fankit like this?? Its different than the Texas Star fankit Texas Star sells 2 different covers 1 top 1 bottom each with 2 fans if you look mine has just the clear plastic top cover with 4 high flow fans and I cant believe how these Comair Rotron fans push air I blow air halfway across the room from out of the ends of this cover it certainly will keep a guy from worrying about overheating.

The only thing is I see where the remote head 3/4 inch plug goes into the amplier theres a 3/4 inch plugin slot for the fan kit my fankit has a couled cigarette adapter wired to it and I see that the amp has a fan thermostat that controls when the fans come on and turn off. I believe that itb was on at 115 degrees and shut off at 105 degrees so instead of fans running constantly pulling in dust and and eventually wearing out Im going to put a 3/4 in plug on instead of the cigarette lighter adaptor and utilize the automatic thermostat unless the thermostat is not part of the internals of the amp ad was exclusively on Texas Stars fankit anyone know anything about this?
