Hi all;
So, to the best of my abilities, I followed some advice. The lighting was reasonable, now I have the lights I use to start veggie seeds over my workbench, full spectrum, very bright, no shadows, very nice. Checked the boards top and bottom, addressed anything I wasn't 100% confident in. Followed through the install notes again, fixed a couple things, changed one thing and fired it up. The lights on the plss worked as expected this time. Checked voltages, ok. Popped some tubes in, set up the bias. Plugged in a speaker and a synth to the input of the power amp and some sound came out. I already had two preamp boards ready, a Zen and Dumble kits. The Zen has fewer connections to the outside world so I hooked it up. it worked. The sound was very bitey, and aggressive, I assume that is the nature of the Zen preamp. Will take a bit of getting used to, never owned anything like this before. Still lots to do with adding options on the power amp, adding the Dumble preamp, effects loop, ect.
When I shut it down after playing the first time, the amp didn't seem to want to turn off, kept playing. Turned it back on, back off, but still seemed to keep on playing. Back on, realized the power light was going on and off as expected. turned it off and kept playing, this amp plays for a while after it is shut off. is the the power supply caps or did I mess something up. My other amps all shut of pretty quick when I kill the power.
now I can rest a bit and just play...
