OTL question

[woody]

Would the GS35B be suitable for an otl? This is a hi power
triode and I am having trouble finding the tube data in a form
I understand. In paticular what would it`s output resistance
be used as a cathode follower?

Thanks

Hi woody,

I personally do not think this tube is suitable to build an OTL.
For an OTL you usually want high current capabilities and good linearity at relatively low anode voltages, which is not the case for the GS35B. Moreover, this tube is designed as a high power HF triode, requiring forced air cooling. Not really what you want for an audio amplifier...

Cheers,

Bruno

Go with PL-519, especially Made in Germany by SIEMENS, if you can get your hands on NOS stock

Or he evergreen OTL favorite the 6C33C-B...

But they MUST be burned in WELL before use....

Hi,

Or use the cheap and cheerful 6AS7G/6080 whcih use regular octal sockets and do not require any topcaps.

Cheers,
