ok... I've been in here before with this sucker... rectifier questions...

[elkym]

Here's the schematic... I've done a couple of other mods, too... and we should probably note that my power supply is actually only putting out about 310-315 NOT 320 like the diagram...

My problem is I don't have 5 volt leads for the rectifier tube... I've got 6.3v leads... I was thinking-- ok, maybe a different rectifier... then decided that's too much hassle in redesigning the circuit-- I've thought it all out-- and the only solution I see is going solid state rectified... but not sure....

So how do I emulate a 5y3gt's output? my 6v6 probably won't handle more than about 400v right? 5y3gt puts out 360...
and I could slip a 5u4 in there... but that jacks my output to 450v... a little much, no?

So how do get my target range of voltage with a SS rectifier?

Weber copper cap?

This article from Mike will provide some answers. Avoid the Weber copper cap...trust me on this one.

IMO, you need to get a transformer that has 5V secondaries.

I was thinking I'd just go solid state/port arthur style... but I need to know what kinds of diodes and resistors I need... point me at something other than tube info, if you could...

T Avoid the Weber copper cap...trust me on this one.

Enquiring minds want to know what led you to this conclusion. I don't use one myself, but it seems like a well made component based on a sound design..??

Thanks, John L, I appreciate your help there with that link.
Anybody else?

You could use a full wave SS rect with 4 1N4007 with two each in series. You will need a choke simulator power resistor 300-500R 10 watts. Then you will have to drop the voltage after that See where you are at after the 10K for screen supply and then what kind of plate voltage you have after the 22K. You will have to probably adjust the values to get the proper voltage.
