The Mojotone transformer has 350v x2 for the first secondary wiring, right? So that's 700v across, supplying up to 150mA. So that's 700v across, supplying up to 150mA. I'm thinking of using a Hammond 290CX which according to their sheet is 650v @ 180mA, so that should be a pretty direct replacement, it would just run a little cooler, right? 5E3 Deluxe & 5F11 Vibrolux Point to Point This point-to-point (PTP or P2P) layout is intended for a blank Hammond style chassis or a 'cake pan' build. You've got to keep everything pretty close together to make PTP work. Keep in mind you can build in '3D' with point-to-point and elevate some components up, over the top to avoid component crowding.
- Marsh Tweed Trem-King A.K.A. Vibrolux 5F11 This is a great Tweed Era 110 combo amp with full warm clean tone that turns up to 10 Watts of Classic Crunch and OD!! All with awesome foot switchable bias vary tremolo AKA Vibrato! Comes standard with a Weber 10' Alnico Speaker! Vintage style footswitch is included!
- The output transformer, filter caps and rectifier tube are all upgraded to handle the higher 6L6 fixed bias output. If you are considering building a Deluxe or Proluxe take a look at the 5F11 tweed Vibrolux. It's not any more difficult to build but it includes tremolo and fixed bias. I'm a big fan of tremolo.

Data subject to change without notice.
Got a nice tweed Vibrolux, built for me by Mojotone. It's a great looking build, but there are a couple of minor issues. Firstly is the transformer/power supply hum. I assume that it's 50 cycle hum, (UK voltage)- can I safely increase the stock 16uF filter caps to say, 22uF to attempt to eliminate the hum.
Secondly, the low volume pulsing from the trem circuit. Is it an inherent characteristic, or can I build it out somehow? I've intentions to slow the trem with a couple of cap changes to make it more usable.
