I spent a summer logging. Yeah, I get it.

Couple points A very fine touch is needed when snugging up the output screws. To facilitate this, I run a sharp tap though the soldered in nuts to chase the threads after soldering.. And, I very lightly grease the threads of the screws. I want the threads clean and very lightly lubricated...

Steve Winwood at Blossom, opening for The Doobie Bros.

Great White videos on YouTube.

Gap erosion most likely from corrosion. Placed a Q-Tip wetted with white vinegar over those deposits for a couple hours. The brass underlayment is showing, the ferrite bottom of the gap is gone. I have no idea how this will affect performance, most likely not good. We'll see. Perhaps internal...

Still have deposits in the gaps that a Q-Tip won't touch. Paper edge is way too thick. Think I'll slice a thin shaving off a tooth pick, make a little soft wood micro pick/brush. Later, gonna spin some Skynyrd.

Cleaned the heads again with Acetone. Not happy as there appeared under magnification to be a deposited polymer and oxide film the acetone wasn't cutting. Got out the old Turtle Wax Chrome Polish and Rust Remover, and started polishing with Q-Tips. Worked excellent, the head surfaces cleaned up...

JBL studio monitors perhaps, for the smaller room. Just a thought.

Joe's rule #1, check your test equipment.

Fix them, you have them, so get them both refreshed with new caps, clean pots and switches, and enjoy them. There are ways to stabilize those vertical daughter boards in the preamp so the joints don't fail. I'd desolder and resolder each Molex pin and socket properly with good fresh rosin core...

At first glance I was thinking COVID face mask.

Absolutely!

Got a Annis Han-D-Mag and been practicing on large and small screwdrivers. There's definitely a technique to correctly demagnetizing a object. VERY easy to magnetize with incorrect technique! I keep a couple strong magnets on the bench for magnetizing larger screwdrivers, and small hand tools...

Made a battery box cover for the 2-AA battery box that's mounted on the rear chassis wall. Looked for a replacement cover or complete new box. No luck, so this'll work. Better than tape.

Modified a old miniature nut driver to fit those weird tamper proof screws that hold the trim plate over the heads. I did look for the correct bit, and even ordered a set. Close, but incorrect. This will work. Luckily the aluminum screws are still in good shape and just need a little polish.

There's always something that needs fixed or maintained! Never stops. Going to cut the grass and start pulling and testing tantalums on the Flukes later this evening. I did get the pinch rollers sent off to Terry yesterday. There are cheaper options, but I think having him do them will pay off...

Temporarily installed the transport to set the single trimmer "reel motor voltage" that's on the power supply PCB, and the single trimmer "control IC clock" on the rear switch control board. Everything adjusted up to spec, trimmers close to mid point of adjustment, rail voltages are good...

Amen on the Rolling Rock, also my favorite. Little Kings for special occasions.

It's alive! Came up just fine on the Variac and a 72 watt DBT. I figure I'm maybe at the midpoint on this if no major problems occur.
