OTL Asylum

This looks like a low power stereo OTL to me.

So it has two RCA inputs and two speaker terminals.

Therefore it uses four (6080) output tubes. Plus another 12BH7.

A photo of the input section as big as the first one would be really helpful.

Either 6080 or 6336 outputs is my quess.

  You need ceramic sockets for those! Since this was built by Luxman they would have used them if intended for that tube so 6080s is far more likely.

    - No photo, but if they didn't use ceramic sockets it would have been unreliable nt - Ralph 09:35:49 03/15/24 (2)
