Once upon a time? NAPA had a spray can of sticker removal that would lift out the solvent in the glue so that all that was left was the rubber solid and it rubbed right off afterward. It was under

Welcome! My first scope was a 502, and I really pushed the bandwidth, using it to look at waveforms on the Commodore PET and CBM computers.? It was actually the reason I joined the group too.

Try Goo Gone, a citrus based product (not to be confused with Goof Off, a paint remover). I have used this to remove cal sticker adhesive from several Tek and Agilent instruments. Be gentle! Rick

Greetings to all. I have recently purchased a non-working Tektronix 2465 (not A or B). Having carefully recapped the power supply which was blowing fuses due to leaky mains input filter capacitors I

Dear all, I am new in this group, so I would like to greet all of you. I am restoring an old tek 502 scope. I have change death tubes, and check everything and now it powers up. Power supply works,

Hi to all, I am new in this forum, a friend of mine tell me about a group of wise nice people. I am restoring an old tek 502 tube scope. And I need some help: Its HV transformer is death, it has a

I can't count the number of times I've boxed up something and then ended up stuffing the whole thing into a flat rate padded envelope to save 50% or more on shipping.? Keeping shipping down is the

A winding can impregnated with epoxy without being potted in it. I restored my early 453 by rewinding, and it wasn't potted. See topic and photo album titled "453 HV Transformer Rewind". Dave Wise
