Finished casing the power supply box today, and I'm really happy with how it came out. Voltages look good, and its ready to rock. Time to start the final assembly of the EHHA box.
Your right John, the heater is from Glass-Ware, and I had vent slots machined by FPE above the o22 and heater supply heatsinks. I made some progress on assembling the EHHA box last night. I'm planning to work on it some today as well. I need to solder on the air-wired tube sockets, and start the final wiring. I'll post of picture of what I get done later today.
Finished wiring the sockets to the EHHA boards. Tried to keep the wires short while providing enough length for access. Looks a little funny, but I think it will do the trick. Here's a photo.
So the EHHA made music for the first time yesterday. I set the gain to 5x (10x balanced) per John's recommendations, and it has the the juice to power my K1000's without a sweat. So far I'm really liking what I'm hearing. Getting very close now to finishing this one off. Here are some progress photos:
The case is a pair of Hifi2000 2U slimline cases. They are nice a roomy and like even better in person if you ask me. I will definitely use them again on my next project.
