once ... back when... I bought a early maybe 1940's DIY Push Pull type 50's, off ebay . It had a 310A input driving a 45 IT coupled to the 50's ..it didn't come with the 50's, it did have the other tubes and a pair of beautiful Globe Type 81 half-wave rectifiers.
.. I had a pair of 50's to use , so I got it running.....Man was that thing loud, lots of power, a bad volume pot made it hard to control.
Presently I run my 50's in my Universal SET amp. I think they more rich than a 45.....But they both share the same single flat plate design, Not like the 2A3 or 300B..... so there you are !!

Tell us more about this universal SET amp of yours! It sounds like just what I need for experimenting. Do you have a schem you would be willing to share?

Vinnie , that amp started as VT-52 cap coupled amp. Then it got Electra-Print IT's.
Now it's Directly coupled ,multi-voltage 6.0Amp DC filament supply. A low B+ 325vDC or Hi B+ 450vDC ,
B+ toggle switch (only w/power off). Bias meter with switchable Left or Right Output tube.
It's cathode biased by big watt variable pot and a big watt wire-wound.
I can dial in a wide range of ma.'s for just about any bias point I want.
Test points for Plate and Grid voltage for each output and a Grnd.
So I can run just about any 4 pin DHT around. I even made and adaptor to run a German made triode awhile back.
Lately I've improved my sound system, so it's been fun going back and listening to my amps and my 26 preamp again.
Have fun!

I actually had a very nice amp that could run multiple output tubes. It as a KC1 > 112A > 45/183/VT-52 and even 50s. I actually liked the 183/483 best. It was a very nice amp. I sold it and kept a 801A but it was a very good amp and I just could not justify having two amps with a lot of money tied up in them. Seemed like a waste.
Yeah GEO
I remember seeing pictures of that amp and you speaking of how good it sound. Yes it was a beautiful piece.... Did you build it ? ...... Whoever ..... nice work !
Willie
Burgess built it. It was really a very good amp. I probably like the 801A amp better but they were both very good. I miss it sometimes. The 183/483s sounded best.
Yes 182/183/482/483's are really nice too, maybe more punchy or punchiness !! .... love them too!
Over the last 15yrs I've often thought of selling that amp, but it just gives me too much pleasure hearing different DHT's.

The thing is it could play multiple tubes. I would have sold the other one.
I kept the one I liked best. Send an email. I may have schematic for the flexible amp. It was excellent.
I would be happy to, but you don't acept unsolicited email. My address is vince@vrhea.com if you find the schematic. I would appreciate it.
ok I changed it.
