michael c	marshall clone i am attempting to build a marshall clone using the schematic found here on ampage. i have the space for a tube rectifier. i want to know what rectifier i could use in place of a solid state rectifier. or if it is feasible idea or not. thanks again michaelc

anon	5v4, 5u4, 5ar4 will all work-- and they all have the same pin-out. 5y3 is too small. I built an amp using those same schematics and I am quite happy with it. About the only change I made was to remove the 'bright' cap on the volume control. Careful layout is critical due to the high gain.

If it were me I would skip the use of the rectifier all together but if you want to use one then I would for a GZ34 like Marshall used. It's the closest thing to a SS rectifier while still being a tube. Most of the other rectifiers seem to "sag" or "compress" to much when you drive the amp hard in the 1987-1959 circuit.

Hope it helps!

And do what? Find a 450 volt battery?

Well you could for a tube rectifier or use a solid state rectifier. I happen to prefer a solid state rectifier in a Marshall but that's just my opinion.

Now what makes you post replies like that anyway??? Are you just hostile or is it your sense of humor and I'm missing it???
