OPS boards arrived safe and sound after getting lost in translation. Thanks Evanc

But, my plans keep changing 🙂

Does anyone know if it is possible to get hold (buy) of a pair of "slewmaster min"/"slewbaby" OPS pcbs?

Can you post a link to a schematic for the ECC88 board? I can't find C10 on any of the schematics I've found.

I think Marc added C10. It replaces C1 with one of those huge "audiophile" caps some guys like to use.

For some reason Irfanview was messed up. Here's a better pic

yes that is. If some one will a smaller IPS board he can just cut C10 area and use middle mounting holes.

I built a pair of the ECC88 boards for 6N1P tubes. Only 3 components need to be changed. I adding the schematic and a pic of the board.

Blessings, Terry

Sorry, The schematic had an error. Basically, for the 6N1P starting with the ECC88 schematic, R6 becomes 4k7, R19 becomes 10k and D1 becomes a 15V zener.

Hey that's great guys! Please share your builds. Funny, the guys with international mail seem to have received their boards first. Those are the ones I worry about.

This amp was named VSHA by Borys. (Very Simple Hybrid Amplifier). It really is pretty simple with few parts but it has a very big sound. Certainly worth the work.

Blessings, Terry
