Looking good. Where did you order the veneer from? Could you explain that process in more detail. Thanks

I will finish the veneer shortly and share my results. Currently have the new veneer on the case, stained, and one coat of poly. Need to smooth and do one more coat of poly.

Am currently reshaping the wood sides for the faceplate - relating to a couple of unsquare corners (wood puddy).

Will be done shortly.

I elected PSA (Peel Stick Adhesive) = Red Oak.

Prepared the original wood subsurface with a urethane coat, sand, clean and applied the veneer. Next applied the veneer (really not too hard) and had good adhesion - PSA is really pretty easy to use. Stain, poly, sand, another poly, then call it done. I like the gloss finish and protection of poly - others may not.

Side pieces are almost done - have one more coat of poly and I will reassemble the unit.

Have enough veneer to do the SA-800 that I recently revived - will be doing it shortly.

Nice work, the 1250 is a lot of fun to restore. Easy access to pretty much every board.

Finishing Up:

Setting Bias = God Bless 25 turn Trimmers (Dead Nutz) both Channels

Here show blows... on top my beloved SX-850

Have New Wood Veneer Here = May Tackle Today.
Sounds Great. FM Stereo Light Does Not Work (did not work before I started). Might post another thread on this. I get FM channels, tuning & signal strength. Have 13vDC on the pin 22 on the power supply, but the FM switch on pin 9 of the IC is not turning on. (am competent but don't want to make things worse).

Going to gift to a co-worker.

Did I say the SX-1250 fell through = got a call today and was able to secure. Can you say next project?

Awesome!!!!!!!!!!Perfect.

it's very difficult to acess the back of this board to do the recap.

Main Power Supply Board. Noted that I added a heat sink on Q12 that I salvaged from a old computer power supply cut down.

Before:

After with New Caps and Relay:

Repasted all the transistors with heat sinks:

it's very difficult to acess the back of this board to do the recap.

With the amp turned up on its side, transformer side closest the table, that board should have pretty good access, once the 2 screws at top of board and another ground screw are removed.
