The 350b would work wouldnt it?
post #79 of 429

Yep the 350B has the same pinout and voltages.

NOS on those could be silly amounts of money.

Current price over $700 each.

I would be happy if I could find them for $700. I am seeing $900 - 1800 for 1.

Oh, so they're even cheaper than the big bulbed Osram PX25s.  That's like a Bluelight special!

    Dear Kevin ,  thanks for the info.  Could you recommend which tubes for each types should we consider?  I am thinking about

     6L6GC  : RCA, Sylvania

     EL34 :   XF1, XF2,  Metal base

     KT77 : GEC NOS

     350B  :  WE 350B, WE367A?

Should this be enough?

Just heard back from Craig.  Looks like the Electra is down to one cap now.  smile.gif

Just heard back from Craig.  Looks like the Electra is down to one cap now.

    I also heard that the performance may be approaching DIY T2 with higher gain to drive O2mkI

The SE version will change from the pentode tubes to triode tubes    ,  that's also good news.

We'll see. Craig did refer to the T2DIY as the "FU" amp.
 

post #87 of 429

You do NOT need more gain to drive the O2 (and I find the T2 comment to be highly suspect)

He means higher voltage swing.

He meant it in a good way, as in top dog amp.  Forgive Purrin's lack of eloquence.  Snow blinded by all that TP.  tongue.gif
