Re: Drake SW4A AGC issues part three

Richard and the gang

I remove (electrically) the old cap out of the circuit before tack soldering in a test capacitor.?

The test capacitors were quite a bit out of spec (I used a 47mf instead of the 8mf drake used) and that could be the issue with having the wrong capacitance in the supply.?

A man with one clock knows what time it?is. A man with two clocks is never sure.

??By tacking in the capacitors do you mean you just paralleled them with the old ones? If you did not disconnect the old caps their leakage (parallel) resistance would still be there. When substituting caps the cap must be disconnected from the circuit. If you DID disconnect them what happened is beyond me. Maybe a cold solder joint that got fixed when the new one went in.
