<div style="RIGHT: auto"><SPAN style="RIGHT: auto"></SPAN> </div>
<div style="RIGHT: auto"><SPAN style="RIGHT: auto">Thanks for all the great ideas! Here is an update on the HO 10 scope project: I opened her up and gave her a good look over, looking for obvious burned stuff, loose stuff, etc. I unplugged the tubes and did a visual on those, and returned them to their sockets. I measured the caps and resistors and found nothing "way out," although several of the hv resistors are higher in value and are on the "replace" list. I found nothing obviously damaged, so I plugged her in and switched her on, again watching for anything unusual. The tubes lit up. I waited, but no trace on the CRT. I decided to let her remain</SPAN><SPAN style="RIGHT: auto"> on and "cook" a while ~ after 10-15 minutes - finally, here came a trace! I have repeated this scenario several times, and I have even put her in the "loop" and monitored my signal FB. </SPAN></div>
<div style="RIGHT: auto"><SPAN style="RIGHT: auto"></SPAN> </div>
<div style="RIGHT: auto"><SPAN style="RIGHT: auto">So, any ideas about what to replace to eliminate the "wait" time? All the tubes are reasonably priced except the 6C10! That one is pricey! (On, and BTW, I do have the assembly manual and schematic.) </SPAN></div>
<div style="RIGHT: auto"><SPAN style="RIGHT: auto"></SPAN> </div>
<div style="RIGHT: auto"><SPAN style="RIGHT: auto">Thanks for everyones assistance. </SPAN></div>

<div style="RIGHT: auto"><SPAN style="RIGHT: auto">Chuck, Hayseed has a recap kit listed for an HR 10, but not the HO 10. But it looks like they would assemble one for me if I requested it. Thanks for the info. <VAR id=yui-ie-cursor></VAR></SPAN></div>

<DIV><FONT size=2 face=Arial>Hi Mike,</FONT></DIV>
<DIV><FONT size=2 face=Arial>Yes, have restored a couple of them and others with the same circuit. Replace the HIV caps and all the resistors in the HV circuit.</FONT></DIV>
<DIV><FONT size=2 face=Arial>The electrolytics are unobtanium, but I cut off the base with a Dremmel tool and install new caps inside. Epoxy the can together.</FONT></DIV>
<DIV><FONT size=2 face=Arial>Works great and keeps the look original. Suspect the 1V2. Makes a great scope to monitor your stereo. Good luck.</FONT></DIV>
