Lazy suit Sunday. Some more tries at plate curves w/ Tungsol 5881 🧵 @coyotescalling.bsky.social

Matching the 5881s with the Metrix U61B and tv10

Preliminary testing some nice tungsol 5881s and some of the earliest numerical display tubes E1T

National Yote day? 🧵 @coyotescalling.bsky.social

Refresh and retro modernization time. Parted out my other bike for the newer parts. Swapped back tech 3 brakes, X0 shifter/der, new chain, headset bearings done.

Purple glow of destruction Soviet 6p3s / 6l6 Gas analysis: very excessive plate current and G2 current. Junk tube now

Extremely delayed suit Saturday / Sunday, Finn turned 1 year old, some noodling, 6p3s analysis scheduled for tomorrow 🧵 @coyotescalling.bsky.social

On the list of procrastinations to work on finally…1950s/60s?? HP 200cd

Testing Soviet magic eyes (6e1p) with the Metrix. (More like testing the Metrix )

Turning on the substation

Spring cannot come faster. Late mx Monday 🧵 @coyotescalling.bsky.social

The things people throw away

Restoration complete 1961 Metrix U61B ex STTA (Service Technique des Télécommunications de l’Air) Over a year of work. Arrived destroyed /dead. Now working. Thank you shadow and voltage for helping when I didn’t understand this thing. This analyzer taught me tons as well

Final cleaning and grease

Sinunasal waveform analysis is inconclusive 🧵 @coyotescalling.bsky.social

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.

2025 done @foxfrommars.bsky.social 🧵 @coyotescalling.bsky.social

2026 means the carpet suck n blo machine turns 97. Hoover 725 is always reliable The 1914 thermax toaster turns 112

TV2-C\U recap pt2

Tv2-c/u recap pt1/3. No more failed 1961 electrolytics causing a loss in screen voltage.

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

Lethal oatmeal is back pleximaxxing Wish I could find the band this came from. Who tf is called killer oats

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
