I'm looking for a copy of the schematic or maintenance manual for the following two Tektronix items: 1) Tek 606 monitor scope .... looks like it's got trouble in the lv p/s 2) Tek 551 Dual Beam scope's power supply .... might make a nice GB experimenters HV supply Thanks in advance for any assistance. Email direct if possible, no need to clutter up the list(s) 73, Lenny W2BVH
