[cowboytta]

Hello everyone,new to the forum and new to radio...only in it about 6 months.
Does anyone know anything about the 800 or where I can find information/manual on it?
Thanks

Not sure on the 800 . Is that a Hybred like the 500 ? Transistors & Tubes ? If so from what a read really touchy on the loading & DON'T like to be over driven . 73 & God Bless Leo Btw Welcome to the forum !

Could use any number of different tubes, they changed those with "Wind" direction(8975) 6GK6's...8908's...etc.. sub's etc.

Thanks for the information 357 and BJ...this one has 30KD6 driving (4) 31JS6C tubes. I think I'm going to pass on it being touchy on the loading and driving. I dont know enough yet to be working on it myself if something messes up. Again thanks.

It's a hot rod without a crash cage.

Calming one of these down so you can depend on it requires some modifications, none of them shown on line AFAIK.

May be a cool toy to play with, learning about amplifier design.

Not so good a prospect if what you want is a dependable daily driver.

Good choice.

I need the receive relays for this amp. That’s the small set. Does anyone know where to find them?

The part number printed on the relay is your only hope of getting a drop-in replacement. Relays that size don't always have the same pin assignment. The specs for the original part will define what can drop in and replace it.

Just need that number to find the specs.

And if you just don't need a preamp, a wire jumper can fix problems caused by the preamp relay. I'll see if I can dig up a picture we have for the relays with the clear cover that pops off easily.

Found the pic. If your preamp relay looks like this one, you can totally avoid removing the printed circuit board from the amplifier this way. Won't have a preamp any more, but the flaky preamp-relay problem will be a thing of the past. The wires are fairly thin. Removing a strand from a thin stranded wire should get you what's needed.
