So, around 6 months I sold the cabinet for my 5F11 Vibrolux. I finally got around to starting a new one for it this week, and when I got the chassis out I decided to do some work on it. It was the last amp I built with the Mojo small parts kits before I just started sourcing all my own stuff. Those big neon blue filter caps had to go. So, the 16uf Mojo caps swapped with 22uf F&T's. And the 22k dropping resistor was a 1/2 watt carbon comp that I changed out to 2 watt metal film today as well. I also changed the PT secondaries again, back to the 315v instead of the 275v taps. Well, I've got to say I like the changes! The tremolo definitely benefited from the filter cap change. It is stronger & deeper than before, and it just seems to last forever, sustain-wise. Measurements, all JJ's: 383v plate to cathode 20.7mA 56% B+ goes 387v, 384v, 296v I played it a while tonight through my Pro Jr cabinet & Ragin Cajun. The cab is 16x18 pine cabinet I built a few years back. I liked it! As big as a Ragin Cajun can sound, it definitely sounds all 10" speaker with this, but in a good way. It's snappy, sounds more like a Princeton Reverb to me. So, here it is mic'd, amp volume on 4, tone on 7. I also ran it through my Cannabis Rex stuck into a 1x12 test cabinet I built a while back. It only around 9" deep and is a little brighter than normal, but the tremolo improvement was noticeable in it as well, so it wasn't just speaker differences.
