Thanks for the info.
Did you upgrade the OP-amp or did Mike do it.
I know you have done some of the work yourself, but if remember right, Mike did some to?
Follow Ups:
Mike did that. It actually looks pretty simple with just a couple of caps and TO-99 style op-amps (can't remember off top of head which ones). But, looks can be deceiving. Parts of the original OP-11 operated the auto turn-on circuit which is no longer used and a number of other parts in that circuit were removed.
Thanks.
I will look forward to some upgrades.
I'll post some pics in the fall!
