RE: If you are looking for better bass response...

Thanks for that info. Actually, I'm imitating the Eico HF81 output, same as the HF14 monoblock amp. I've owned, worked on and restored 4 HF81s (now sold). I have some pretty good vintage OPTs. I guess I'll stay close to original R and C values.
If I find another trashed HF81 (a hard to find item now), I'd probably restore or rebuild, as I have before. Fun to work on.

Cheers
P
