In a word, no Jeffrey. Presently there are jumper wires everywhere but a reasonable ground scheme. One thing I noted was that the grids of the 2C34 go negative to around 26v DC with full AC signal. Something is causing it to go into near cutoff. I knew it would be a tricky valve to drive; will check for parasitic osc and do more tests today.
