I actually figured out (I think) what R170 was doing. It adjustS the horizontal symmetry of a square wave signal. You adjust for the same length (pos and neg sides). And that also affects the

Rectifications: 1-R170 has much effect. I wasn’t looking for the right thing. 2- C287 has still no visible effect. 3- -25db bleed is still present 4- The picture above is because I messed with

According to the manual R170 compensates for small offsets in the op-amps that control the positive and negative constant current sources that control the timing. The offsets are most noticeable for

Ok, so you suggest I sweep each digit for a signal at its input? At the ribbon cable connections then...

Dave, I know. I have been a seller on ebid for almost 2 decades. I have never sold anything and I have never bought anything. It has always been ebay or for my books amazon. I don't like either

I appreciate the tip (it was new to me); I keep hoping for a reasonable alternate to ebay, but it would need critical mass before I would browse there regularly or list things myself. -Dave

Dave and et al, Just a thought! GOD Bless and Thanks, rich!

I just looked at that- not a whole lot there I'd want to buy.  Seems like everything I looked up was mostly old advertisements.  -Dave 

Hi satbeginner The FET I used is not plastic one and I used heat conductive paste. Looking at the space available I think I can add a heat sink but I have to check if I can later on put back the power

Actually they're running behind. As they notify sellers, the seller will have 30 days (as I recall, might be longer) to get qualified for it. They said there's a good chance they won't have everyone
