Mercury rectification Asshole tester done

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

Metrix U61B Monday

Suit Sunday Brain buckets….contains 1% yote cells. A redo because Bluesky won’t let me tag people as usual 🧵 @coyotescalling.bsky.social

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

Testing 2x 6k6 for a certain creature and his Vtvm. @voltagehyena.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

L1-3 - working still

1961 Drager Romulus narkoseapparat complete. 40 something pounds of chunky copper A very nice 50s Unigor 3 from a stinky yeen @voltagehyena.bsky.social

Double checking measurements with the cinder block

Long overdue Neuberger RPM370-1 function test.

Mash all Monday + the Marshall mutt

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.

Good yoting 0 effort suit Saturday Glorious Siemens Selenium Rectifiers. 🧵 @coyotescalling.bsky.social

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

Mesa Boogers Monday

Got this new French pastry....tastes kinda strange. Must be old or something. Camemberts 🧵 @coyotescalling.bsky.social

1st recap ever / metrix recap pt 1 of alot. More caps to order now. Works fine, less chassis voltage, Ob2 ignite sooner, tubes in general brighter? VIDE key tested, seems ok. 6sk7 no vacuum. Tbc..

Romulus restoration continuation Lots of plated brass Date code of May 1961 found?

Metrix U61B short demo pt. 2, testing.

Metrix U61B short demo pt 1 Set up.

The Metrix U61B is revived and made its first ever measurement in probably 30+ years. Almost 1 year ago it arrived to me smashed and trashed, totally dead. Now working again. Still more work to go (new caps, resistors,etc). Patreon saint of OB2 + 6AU6 @shadow-hyena.bsky.social

wireless connections

NOS JHS Military Sylvania 6au6 and ob2s for the metrix u61b. Sadly did not fix the problem but definitely runs better now.

More cleaning

The collector of dust, rust, dirt, dried 65 -70 year old grease. I hate onion switches. Layers layers layers Will be rewarded with new grease if it can eventually make a measurement

French pile metrix u61b continued Waiting for tubes Cleaning Deoxit Stupid flappy dangling garbage cough i meant tarage filament switch.

Metrix U61B the good, the bad, the ugly The good: G2, G3 voltage now works The bad: anode goes off scale (pic 1) The ugly: changing positions of the 6au6s causes the G2/G3 and Anode meters to reverse. Time for new 6au6s. Wish I had my tv2 to leakage test these pos.

French complications. And the stupid switch

Standard oscilloscope protocols FSF 🧵 @coyotescalling.bsky.social

Who needs ikea furniture when you have 400+ lbs of cast iron, brass, glass, etc. c1954-1957?? Drager Romulus. About 80% completed and to be restored. Survived its long trek from across the pond. The ultimate end table/booze storage.

New mesa boooooger settings

Neuberger Rpm370-1 weekly function test and analysis of 53+ year old hot Mullard /Mazda El34 garbage (original power tubes from the vampower) Conclusion 1/4 broken filament? No matching Vukuum/Gas test rejection They do work...ish
