Looking for a tube amp

[CbRadiosPRONTO]

I have a buddy with an RCI-2995 (new one-4 MOSFET finals). He is looking to get a tube amp. Any suggestions or leads on a good match.

4 or 8 finals?

The radio or the amp?

The radio has 4 MOSFET finals. He's not set on a certain size amp. I think it's just a matter of value, what's available and what will work with his radio.

Here are a few listed around Louisville.

Palomar 300A Linear Amp Works Good
Heathkit SB 221 Linear Amplifier **2K amp**$REDUCED$
Linear Amp Works Good (Home Base Amp 110v)

Nice Heathkit! The other two are too small for the 2995 radio. That heath, though, wow!

I can't in good faith recommend an illegal device for 11 meters but if your friend was a ham then I would highly look at the sb-220

I was thinking those radios had 8 MOSFET finals. Never mind.

IDK,........ does a 2995 even have a keying circuit or will he have to build one?

Good choices except for the DRAKE L-7/L-75/L-4/ L4B:....no amp of DRAKE should be relegated to such dreadful service as 11m

Single gs35b would be nice but buy your spares while you can. An sb220 is a good ssb amp but not enough duty cycle for an AM hammer. JMO. There some nice amateur amps out there with big ceramic tubes but check price and availability before making a purchase.

But It is an amateur radio it even says so in the advertisement

Even PSK 31 capable???

All kidding aside and back to the topic, No single valve 3-500Z will handle that amount of drive the radio has for output.

Need at least a pair of 3-500Z, and since it is a mosfet best is not to detune them for lower output. Pair of 3-500z only needs 85 watts input drive for full output if the tuned tank is designed efficiently.

Other option is using an input pad. This will reduce the amount of drive into the amplifier and the radio will still have full output.

Then again if you can find an old 3-1000Z, or 4-1000Z, that would be a good tube to use.
