Thanks. Does it mean that you have zero volt offset even from the start?
-
Anyone that have tested the opto servo. How does it work?
-
You can’t just replace the mpsw with the 2sa/2sc components that way, can you? I think their pin layout is different.

Great work! -
Rebuilt a Blue Hawaii to Grounded Grid - seems very promising.
-
Replaced 2sj79/2sk216 with ksa1220/ksc2690 on one Blue Hawaii and one DIY T2. No negative surprises so far.

Looks very interesting. Would it be possible to have some pictures of the inner layers? What might the maximum voltage between layers be? Beautiful symmetry of the board.

Blaha!

OK, post deleted.

Well done. Congrates. The blue electrolytics, are they from the group buy?

As a Carbon amplifier I just use a trimmer to control the offset. Yes, it’s 0603 LEDs – TLMS1100.

A picture of my attempt to build a Circlotron driver.

Absolutely magnificent!

Congrats, well done. Enjoy.

Thanks. Just so I get this right. I assume it's 9.5V from pot to the opamp - not 9.5V from output of amp. R6 and R7 are 120 ohms? (I've a schematic showing 100 ohms) so that gives some 25 mA. The 100 ohms pot for Offset is used when... just to get above in range?

What is the procedure setting up the Circlotron using Offset respective Output Stage Bias trimmers?
-
Is it possible to have feedback from driver output instead of Circlotron output or will that just end up in a disaster?

Great work the new T2 power supply.
