Tom & Bert: Thanks for the info! Yes, the 2235 is a fine scope. I believe I brought one with me ( i., e.< carried ) one service calls in the 1970's. Heavy, but essential. Tom: I will investigate

Thank you for this list. And on a broader sense, for the education. This has been quite informative for me as a newcomer to this part of the electronics field. The comments and conversation have been

Hi Russ, I won't be any help beyond this point since I never owned a 465 or 468. Do you have a way to measure the AC current drawn on the power line with a Multimeter when you turn power on. If it is
