My New/Old Fender Vaporizer Amp.....

Post by zozoe »

Greetings all~ Well, I've gone & done it, again... I scored a Vaporizer for 'round 3 bills, loaded with 2 WGS 20w Veterans, & though the Vape mode is just a tad crisp & fizzy, the gain is fab in the normal mode!! My ONLY gripe is that there's practically no low end to the amp... I plugged it into a few great 12"ers, closed back & open back, & surprisingly no luck,...

So, great gain but no chugga chugga to it... Yes, it would be an easy fix with either a GE-7 or my Guyatone para eq on a soft 'q' & voila!!
But if one WERE to go under the hood, I'm certain that a tech could tinker with a few values. I haven't look at this one yet, & i don't perform mods!!, but typically Fender's PCB are a bit of a nuisance to get around, but again I'm no tech & I'd leave it in some trusted & willing hands.

ANY tips or leads as to what simple component value swap or two or three could get this done?? As for the Vape Mode fizziness, I'm equally confident that there's a tweak or two, as well as the option to forget about it.... I'll do a search for a schematic so I'll be able to follow along with any hopeful directives. As it sits, its got no UMPPHH,, & it's a heavy bugger🐞

Many thanks in advance~

For some odd reason each output plate of the PI feeds two .047 uf caps in series for a total of .023 uf or so.

You might try simply jumping out one of those on each plate and see how much that helps increase the bottom end.

Then again you only have about 14 watts that those 2 EL84 output tubes can make and only 2 ten inch drivers, so I don’t know how much added bottom/ chugg your going to get without things getting mushy.

These where not designed to be a chugg chugg heavy metal amp by any stretch of the imagination!

Not screaming like the passengers in his car!

Cutting out a man's tongue does not mean he’s a liar, but it does show that you fear the truth he might speak about you!
