What's that 6GB3A CSPP thing in #138? Which finals does it feature? Any schematics available?
Best regards!

You can find article about this amplifier in the big archives :

Have a nice day 🙂
Thanks! Unfortunately I don't have my Japanese dictionary handy at the moment 😀.
What's that 6GB3-A tube? Cannot source any datasheet, only of 6CB5-A, which also is a sweep pentode, but with all glas envelope and Magnoval socket.
Best regards!

Thank you, Davorin!
I see obvious similarities to the more common 6CM5/EL36 sweep tube, of whom I've been thinking as I saw the pictures.

Thanks Analog_sa nice kind words!
All glory is for Distant Past Old Radio Boy-San work efforts to inspire hobby amateurs,
preserve and distribute DIY educative knowledge writings about audio tubes 😀
Not always easy to read but with lot's of curiosity and research we can build many amplifiers only from all archived schematics.
If photos show Tango or Tamura brand transformers and chokes then check specyfications , parameters catalogues.
One example this is Tamura 🙂
