Dear Kris Blue Nz, I have been reading all about the lvps of 1741a so brilliantly analysed by both of you.
Now I request you help me with information to solve my problem in a 1741a oscil I got recently.
Unfortunately the lvps is smashed up and the transformer is the only part still ok.The HV unit is ok. My question is will the other section ,two channel amplifiers,time base system, etc. be worked by supplying the necessary voltages from an external source. Once I am sure they work I think I can search for an lvps. I do not know the voltages to be supplied
as I have no clear schematic of the boards. The one I got downloaded is not clear. I saw some of the postings of lvps and hv supply schematics which are excellent. I thought I could request you to send me the particulars of the voltages and where I should feed them i the
other boards and see if they function. I have a Tek465 and wavetek function generator.
You are experts in analysing the 1741 and surely can help me.
Best wishes for a Happy Christmas. Thank you. ATSU 13th Dec 2013
