Finally got the resistor stock organized. Zener and regular diodes will go on the top 4 rows with the 1 megohms.

Sorry I’ve been lacking on the posts lately. Pretty new to designing circuits, but in this one I used a ne5532 to test transistor gain for matching (critical for good output in input and amp stages). I misspoke when I state they have 12v to the base. The chip controls the base input to force equal current across calibrated resistance and my voltage output on the tells me the gain differential.
Anyway…happy wiring!!!

Man, the cold calls are really starting to flow in… I might need an answering service soon. 😂

The Yamaha A-10 is finished. This one was a bit a bigger job, but tons of fun to bring these old gems back to life!!
