I swear the last fella that worked on Tim must have had stock in a thermal paste company. Took ages to clean all the goop out...

I think every CRT TV repairman had a Weller Expert.

That last 700b that I WOPL'd had a ridiculous amount of thermal paste on the TO's.
It was all original, and they troweled it on! My least favorite job on a rebuild, cleaning
all that from the cooling fins, chassis, and everywhere else it gets into.

 

[AngrySailor]

I was just wondering why tf he was putting thermal paste UNDER the CPU... then I realized... good one Mr.Rye!

well I also have this disaster here…..I need a Sencore TV analyst, a Beltron, a Pomona HV probe….I have the big Simpson meter and a B&K tube tester around here…..

Holy Smokes, you fire that baby up, and you’ll be watching The George Gobel Show, You Bet Your Life, Toast of the Town, I’ve Got A Secret, Arthur Godfrey’s Talent Scouts, Uncle Miltie, The Life of Riley. and Your Hit Parade!!!
Jack Benny will be in there somewhere too !
That’s an oldie but a goodie!

That video is false!

We all know they used a caulking gun to apply it!

Fake news!!!

Why did you decide to WOPL a 4 fin??

 

[mr_rye89]

Why did you decide to WOPL a 4 fin??

yeah, both amps are 4 fin. I’m WOPLing one and selling the other……

 

[mr_rye89]

Is it a good idea to insulate the transformer bolts on a 400? Why insulate the transformer bolts?

 

[WOPL Sniffer]

Cures eddy currents

 

[WOPL Sniffer]

or at least cuts them down.....

 

[George S.]

Three ways to do it. McDonald's plastic straw, or thin clear packing tape( Don Watts Abundant idea), or get smaller diameter bolts and use heat shrink(I have a thread about this).

Glen said the early Dual 500s used a straw, later ones used stepped washers. The 700 Pro I WOPLed also had the stepped washers.

 

[wattsabundant]

An extra benefit of rolling the packing tape on the bolts with your thumbs and index fingers is it may take you back to activities you did in the 70's.

 

[J!m]

I never rolled tape onto bolts in the 70's...

 

[mr_rye89]

I didn’t do any activities in the 70s……

PROTIP: alcohol removes thermal grease, Zep removes anodizing…….
