Broken bolt removed with only the most precise surgical instrumentation. I will have my 4 rubber feet Last 50k resistors installed. Electrical portion completed. New amphenol octal socket working Only cleaning and greasing to go

New socket time. Hopefully no more 5y3 problems because of Bluetooth wireless heater connections. NOS 1949 amphenol socket.

Cosmetic update No longer fugly

Trying to get the Metrix U61B to work w/ 9 pin tubes. Socket on Camembert 1…bad connection. Heater won’t get voltage. Camembert 2… same issue until cleaning but also has a better socket. Heat shield in the way. After some force…now it works.

Happy low kwality suit Saturday 2 nice NOS RCA 6v6GTA 9/1960. Tv10 and the Metrix U61B agree

осциллограф с1-35/ c1-35 oscilloscope first tests. The Teslas mysterious “sine” wave has successfully been found Tek 69 with the Tek clone

осциллограф с1-35 / oscilloscope c1-35 made in the Ukraine 1969. A very overbuilt and extremely well built Soviet military scope similar to a Tek 321a. Can run on 220/115v ac or 26/14v dc, max 5Mhz for the bandwidth. Thank you for shipping it safely @darekyl.bsky.social

Function again Anode voltage ✔️

Finnegan is very (un)threatening. The solution was to use the paper press and turn him into a lawn ornament because it is more scary. That is all. 🧵@coyotescalling.bsky.social

Never posted the completed resto of this. C1958-59? Drager Fabius M / "Feldgroß" Nargoseapparat. A field use variant of the normal Fabius originally designed for the Bundeswehr / Civil Defense. Somehow this was exported to Peru. Sat in storage its whole life well preserved.

Recapping the metrix YET again. So it stops shocking me w/ 84-110v almost every time I plug it in. Put the second spare in and changed polarity even though it shouldn't matter. Now it seems to not run like shit...or trip its breaker when turning off DC. Vornado fume extractor

Recapping pt2. And inconveniences. Thank you for the shocking information that you are displeased

Mail day. Metrix caps time

200 dollar enduro shit box has been revived from long term storage to see if it works. Wish it didn't have such a ridiculous seat tube height. Geometry is so good yet the seat tube is equivalent to like an xl despire being m. 26lb speed weapon minus the seat up my ass 24/7. Working ish John deere
