feed back caps
--------------------------------------------------------------------------------
i am working on a sunn 200s,, (dynaco mrk III circuit).
on the feed back loop it has a 1000 ohm resister and a 750pf cap together. the 760 pf caps are hard to find. can i use a 680 or and 820 pf instead, or perhaps 2 390's?
thanks

The value of the feedback cap is not critical. 680 or 820pF will work.
