Hi,
Actually only 12 of them in the GM100TL and 32 of them in the GM200.
As for actual circuits using these...never seen any.
Cheers,
I believe the Graff uses 20 PL504 in the O/P OTL style!

Hi,
Imagine....errrr, yes....provided someone else is prepared to foot the electricity bill.
The GM 200 are stereo amps, 800 Watt power consupmtion idle, 1600 Watt at full flight.
Mind you, mine aren't too far off.
Cheers,
Could you imagine two monoblocks with that lot on!

Braun CSV-60 used those tubes.
My friend has one,made in 1957.Sounds quite good.
It is push-pull design,just one pair for each channel.
As I recall ECC83 is a driver tube.
I think I have PDF with schematics of this amp.
Do you still have the schematic?
If you do, then may I please have a look at it via email?
Thanks!
There must be some mistake. The PL504 didn't appear until 1965. I can still remember my first sighting of one in 1966zygibajt said:Braun CSV-60 used those tubes.

Hello ,
Klein und Hummel had many amps with this tubes , first they use EL 36 , then came EL 500 ( PL 500 ) , EL 504 in the same circuit .
The EL 36 version is the K +H VS 70 , the VS 71 is the newer one with EL 504 .
Also their studio mono amps V 30 were build with EL 504 , in all these amps the driver tube was ECF 80 with the triode as phase inverter .
There were also amps from Telefunken , PE and Elac with EL 504 in the sixties .
I think , I have all these circuits , send me an E - Mail .
Regards , Alex .

Check out Mr. Kainka's website

He has some 3 circuits using the PL504, one is a high voltage plasma arch (can't remember the name of the thing right now).
I made one , but the sound was very very low, could be the trannies
