peter	Re: bias/rectifier observations/questions I was planning not to bypass the effects loop stuff when it's not in use, purely because that is the simplest solution. The post-effects gain stage is just the usual stage but with Rplate=100k, and Rcathode=6k8, not bypassed. I will likely end up optimizing the 6k8, I picked a fairly high value and unbypassed because the amount of gain needed isn't all that much. So if you compare the total gain for this, I will be dividing down by about 100, and then multiplying up by about 10, so there's less gain than without the loop there, but it seems like there's far more gain than is actually needed to drive the amp to full output anyway. More on this when it is finished/tested.

I was planning not to bypass the effects loop
stuff when it's not in use, purely because
that is the simplest solution.

The post-effects gain stage is just the
usual stage but with Rplate=100k,
and Rcathode=6k8, not bypassed. I will
likely end up optimizing the 6k8,
I picked a fairly high value and
unbypassed because the amount of gain needed
isn't all that much.

So if you compare the total gain for this, I will be dividing down by about 100, and then multiplying
up by about 10, so there's less gain than
without the loop there, but it seems like
there's far more gain than is actually
needed to drive the amp to full output
anyway.
