Great news, folks.?

After finding out both A15CR1 and CR2 were shorted, I replaced them with 1N4003s, and all rails are now coming online in spec?(while having the board out, I also replaced all 10uF caps). Now the?+15V is just a hair off at 14.987V (should be within 0.01V of 15V), but I can't imagine that's a huge deal.?

However, I don't seem to see any signal coming out of it. Learning how to use it, so take that with a grain of salt.?

Well, after finally taking this apart (I'd post pictures, but I am a bit ptsd'ed...) I have two shorted diodes on A15 - CR1 and CR2.?

I am thinking vanilla 1N4148 would be OK in this position - thoughts??

Thank you,

Radu.?

Raymond, Clay,

You both sort of got beat by a hair with the 4 youtube videos Clay is talking about. Must be this:?.?

And yes, I take back my statement on the overall assembly design of this unit. I didn't know there's just one SMA connecting?the shielded modules (there's actually several in my unit as to, I think, the youtube sample, but they're not rigid lines), but overall, it's a breeze to take apart (once you know what the correct path is).?

Thank you both! On to the work for me.

Radu.?

I would not call this unit hard to service or a poor mechanical design.? Pull the big aluminum hunk and you have lots of access!? The synthesizer module has 3 long bolts holding it in.? Remove the SMA Semi-rigid coax cable from the module's backplane then pull the 3 screws in the middle and you can lift the synth module and set it aside with the other cables plugged in IIRC.

So my memory served me right!
