Title: EL-84M
Post by: jim on June 17, 2012, 05:54:58 pm
A buddy of mine picked up an Ebay Victoria Victorette sight unseen and unplayed. It sounds like it could be a great harp amp, sort of like a 5E3, but it has reverb and bias-vary trem.  He wants me to make it cleaner.....Well, needless to say he does not deserve this fne amp in the least bit. I tried those Sovtek EL-84M's for the first time and they replated in this amp. The cathode resistor is 180 Ohms and the plate voltage is 270V.  There is no schematic available.  A new pair of regular EL-84's works just fine.  Do these EL-84M's have different spec's?   Do you think these tubes are defective?  What do they sound like?   I did try a 5751 in the V1 and it did clean up just a little.   Jim

If the other EL84s work fine , then EL84Ms should work fine too. The ones that were tried were probably bad

I think that would be a big mistake.

That amp was built for it's sound as is, with verb and bias trem.

And why would a amplified harp player want a cleaner sound? If that's the case just play throug the PA.

IMO, he should sell it to get $$ to buy something more to his needs. And then do what ever he want's to do to it untill he's happy.  

I would _not_ try to make that amp _cleaner_ or anything else than what it was built for sound/tone wise.

This is not and old amp, but a new amp built to be/sound as is. Which someone would/will be _very_ happy with as is.
