Hi All,

sorry to stupidly ask here but I got lost in the several iterations of the amp..

Could anyone kindly link me to the latest iteration with 1 OT-pair only ? Would PCB's for that still be available ?

Thanks in advance,

Max

Shaan,

I am unable to find the build thread concerning the V4 (single output pair)...

This is the v4 thread, there is no separate build thread.

If they both show between 1.7V to 1.9V in multimeter diode test then yes.

Thanks Shaan,

I read 1.95V for the greens and 1.80V, I will give it a shotas is, voltage drop seems high to me, it's standard Lite-On LED, nothing fancy.

4 more PeeCeeBee built, transistors reversed as I am using 2N5401/2N5551.
