    This weekend if I have some time, I'd like to try out the paulC mod in my 5E3. Based on this schematic, it only requires an additional 2.2M resistor. My local RatShack sells 1 M resistors, is it ok to just put two in series? The value will be a bit off, and ofcourse I need to pay attention regarding bare wires. I guess it's ok, but just in case I'd check here.

    I have built this amp myself, so I am aware of dangerous voltages inside an amp :p

    well if you really want to get creative you can throw a pot in between the two 1m resistors

    usually 1m+1m is close enough

    The two Megs in series will work for most purposes. A bit ugly but it will work if you promise your amp you'll get the real thing in there. And preferably at least a 1/2W if not 1W.

    I haven't had the time yet, so no report on how it works.

    Looking again at the schematics, I think it should be not too difficult to include a switch to go back and forward between the cathode bias and fixed bias. Has anyone done this?

    It increases the headroom slightly.
