$400 maybe $500 tops. Since it's modded for only 10-11 meters. Limited on who will be interested in it.

That amp should dead key/ carrier 250w and modulate up to 1200-1400 pep. If your dead keying 1400-1500. It's going to die a quick death.

If you run into anymore of these. I have 2-3 of these brand new transformers.

Question on the amp. I see you have a glitch resistor in series on HV. I normally do this on triodes. But on tetrodes I've heard this is a bad idea. I know it needs some kind of resistor in series to limit current if shorted. It should be shut down by some other method or hold just long enough...

Wish I would of known in advance. Got a couple of brand new blowers and a few bias/ screen transformers that I removed out of some Johnboy amps.

The box should not dead key 500 with only a 2w DK into. Variable or something is not right. If your bird meter does not have a peak kit installed, you won't see 1000w pep out.

It probably won't last long with a Connex doing 30-40w pep. I'd say turn it to low setting, but you'll just burn up the resistor used to swamp/bleed off drive.

I only know, because I keep getting so called newer builders amps in and they are not even close. Had to redo circuits and figure out designs for each.

Not the same electrical parameters. Will tune different. At least on the 2879. Not sure on the 2290's. Single driver 1446 also tuned a lot different. I mean a lot. Did a single 2879 HG as well, it was a totally different animal as well.

I watched EBay for a long time and found some good used ones fairly nexpensive. $30-50 each. All for less than the cost of a single device. To me was worth it. Forced me to To do some reading and expand my knowledge base a little.

Also on the trimmers, the 464/465/469&4615 caps, they work good. But they have been known to arc while in use. Especially if compressed nearly all the way.

Correct I have to tell you up front. If your doing this to save money, then forget it. You'll end up spending twice as much the first few times to build the amp as you have to buy the stuff then after you get working, you have to buy more. Remember certain places have a minimum order. Plus a...

A couple of meters, so you can watch input vswr and output power at same time. Few extra watts on output isn't worth it if input starts to go up. Also need a power supply with a current meter and voltage meter. This will help when tuning if doing the math, you can figure out efficiency. (...

Agreed. But without some kind of clamping circuit. Still not a good idea. Ppl don't listen. Personal use only. I bought some real bird attenuators to put inline to compare to my home brew resistor attenuators. Just to compare 6db,10db, 15db and 20db. I wanted to compare my networks to the Bird...

Yes, but most don't realize if it's set up for 25w in, do not exceed. It is not like the bipolar transistor. While rugged on output. It is super fragile on input. It will die a quick death. Like 1-3 keys if overdriven. I tested it once. 2 keys with just a few watts pep over the 3-4w...

So true. Majority go for cheapest first then wonder about reliability after failure. After it's too late.

BBB, those are 2w potentiometers. Just a heads up. 100ohm.

Waving right back triple 2.

I agree. Most everyone cuts corners somewhere. Or worse they just copy someone else's design and call it good. Even though it's not an exact copy and don't take into account the extra inductance due to leads. And your right, the better ones refuse to sell at cut throats prices like the rest...
