I am about to start to recap it and it has grey boxes with the capacitors so are they chassis grounded and are any caps higher voltage then 450v.

The schematic will tell us how the caps are wired. If in doubt, post a snip** of the section showing the capacitor.

As for the voltage rating, does the schematic list any DC Voltages?



** open the file and crop down to the area in question. Then scale to 600 pixels or less on the longest side---so the file size will be small enough.

I would need to see all or part of the schematic. Ideally, post a link to the schematic. Otherwise, post a picture of the portion of the schematic that shows the electrolytics.

This is all I can find using Rogers and "841". Does this match up to what you have? (Chassis number 841)

The schematic at Radiomuseum is one of the worst I have ever seen. If yours is better, please send me the file. (i'll send a PM with my e-mail address)

If yours is no better, I suggest you make a new schematic before starting work.

I suggested earlier that you may have to draw your own. I would start with the one that is available, but draw it in the modern format...showing the tube PIN numbers, etc.

Nice!!---where are those from?

for SP: The + side of the 2 main filter caps is the top end on the schematic. 450-volt rating is fine for the electroltyics
