AVR Scope Clock
I've seen these XY oscilloscope clocks out there before and wanted to pick one up. Unfortunately, the Dutchtronix website shows "out of stock." Does anyone know if these kits are still being made, and

Back feet for 335 scope
A while back I found a guy named Bob Haas, who was selling molded 400 series feet on eBay, try and make up some 314 feet (same as the 335.) I sent him a couple of feet and he made a couple of sets for

My dad sold Frantz oil filters (held a roll of TP as the filter media) back in the 70's as a side gig to his teaching job and those things worked great. He had an old Ford 352 engine with over 300K on

For a master of roadside and shade tree mechanicry like you and me, doing the head gasket in a weekend (assuming it needs no machine work) might be worth it. If you have to pay to have it all done it'

Jim, Thanks for the reply. The plugs, leads, cap & rotor were about 6 years old and had about 28k miles on them. However, I thought the same thing so I replaced them all. It didn't help. Someone here

Tektronix 475 beam trace length issue
Thanks for posting that back. That is R1202 and, according to my B250000 and above service manual is a 1.82 kohm 1% resistor. I don't know what the ramifications are of using a slightly higher resista

Update! It looks like Mr. Michael Terrell is the winner on this! I replaced plugs, cap, rotor and wires with all Nissan OE parts. No change to the ignition noise--not surprising. No biggie, though. Th

Scott & Ed, Thanks for the replies. I looked at my ESR chart again and for a 25-50V cap at 0.47 uF that 3.2 ohms is actually well below the threshold for a bad cap of that value. If I were to just go
