MUTRON II PHASER ISSUES

Lumpy58
Against my better judgement, I decided to build this.  Early on, I had some passthrough audio and some weaker phase effect.  Then I didn't.  Used a 7660 for a -9v inverter, off the GFX layout.  Worked fine by itself.  Didn't like the board though, and only gave me -0.15v.  I have quadruple-checked values and placement on the board(s), and only have solid light on the LEDs and no passthrough audio.  The 7660 would get very hot, and I feared I fried it.  Now it only gets -2.35v alone.  Built a 555 inverted, tested out a -8.65v.  Tried it with the board, now I get the same (-2.34v), no phase or passthrough.  Using 5339 LDRs (all I have), work great in all my other LDR builds.  7660 VR worked great in my MUTRON III build.  Using yellow diffused LEDs, except burned one so subbed in a greenie.  Still no sound.  Only board subs include 2n2 parallel with 4.7n to give me 6.9n (for all 6.8n caps). Used a 330p in place of the 820 (biggest I have unless I go 1n.  Have gone over cuts and traces, some dremmel goofs fixed and continuity is good (not the neatest work, but my hands are old. voltages for JRC4558s:

Additional info:

Took out the 4558s and checked each in my TS9 clone.  All work fine.  Tested voltage inverters and both the 555 and the 7660 work fine.  -9.05v (with the 555) measured on pin 4 of all ICs (with chips out).  So now?

Could not resolve this one.  Off to the bone yard.
