<BR><BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px">I have a Tektronix 535A Oscilloscope that recently quit working. As I have
<BR>considered building some of the tube synth circuits that are currently
<BR>circulating, I thought it would be neat if I could keep this giant old
<BR>scope working to go along with them. Does anyone have any idea where I
<BR>could get the schematics and technical manual for this beast? If I can't
<BR>fix it I'll have to scrap it. Given it's weight, I doubt that selling it
<BR>is an option.</BLOCKQUOTE>

<BR>I used to have a 531 that I picked up for 5 bucks when I was maybe 15. Those series scopes must weigh at least 50-60 pounds, maybe even 80.The best thing to do these days with a beast that size is strip it for parts and throw it out, in my humble opinion. Which is what I did with mine when I got tired of it taking up space. A decent solidstate scope that's 5 times the bandwidth and 1/3 the weight can be had pretty cheaply now. I've got a 465B rackmount in my rack full of audio gear that I picked up tested and working for $135 at a flea market, and a 7704 that cost maybe $90.
