July 31, 2026 - Got a ultrahigh sonic cleaner last week - put the knobs in and they turned out pretty good.
June 20, 2026 - Picked this up a week or two back - the batter was corroded and it didn't have any probes - got a C cell battery holder and hooked that up - the Ohms setting the the DC voltage setting is working. Need to mount the C battery holder and may need to go ahead and replace some capacitors, but at this moment it looks like it's working fine.
July 26, 2026 - Worked on the power supply schematic.
February 2, 2026 - Changed out the broken current switch - unfortunately I used a NO momentary and it calls for a NC momentary - the good news is it's not a bad replacement so I immediately ordered the correct switch and it has arrved (2/5) and I plan to change it out on 2/6 or 2/7.
January 3, 2025 - Received the 12v bulbs that I ordered from Amazon and one worked great for the dial light. They are titled "MEETOOT 10PCS Bayonet Mount Bulb P13.5S Bayonet Small Bulb 12V 0.25A 3W Suitable for Flashlight and Emergency Light". https://a.co/d/0zGJFUH
December 6, 2025 - All the tubes are here and I lit up the filaments with 8.2V at 3.5A.
November 28, 2025 - The VY-63 tubes should arrive today along with the PL-150 connector. Still need to order the VT-62's (801 tubes). Looking forward to powering the filaments up in the next few weeks.
November 24, 2025 - It's here.
November 16, 2025 - Yet another project - a BC-223-AX - doesn't have tubes and purchased a TU-26 tuning unit with crystal cover.
July 16, 2026 - Picked this up recently and initially it powered on but only a single dot on the scope. This evening I checked all the tubes to see it the heaters were working. I removed a few and sprayed contact cleaner on them and reseated them. I was able to get a solid line with nothing attached. I hooked it up to my audio generator and was able to get a sine wave as expected.
