At some point next year, I'm looking at retubing my 6505+ combo's preamp.

Now, I have no idea what makes a 'good' preamp tube. But, at this point I'm thinking a JAN Phillips 5751 in V1 to improve the cleans a bit... beyond that I don't know. JJ? Tung Sol? Svetlana/=C=?

I'm up for spending up to about $80, and there are 5 preamp tubes including the PI.

LTD MH-400 with Gotoh GE1996T (EMG 85/60)
PRS SE Custom 24 (Suhr SSH+/SSV)
Ibanez RG3120 Prestige (Dimarzio Titans)

Audient iD22 interface
Peavey Revalver 4, UAD Friedman BE100/DS40

5150's tend to like JJ's, you can mix and match a bit if you want to, .

from my experience with JJ's is that they tend to be a little darker sounding, which pairs to the 5150's nicely, and have extraordinary long life.

as far as the 5150 goes however, i would either do or get a tech to do a bias pot mod. peavey biases cold, with the bias pot mod, you could get them running a little bit hotter and get a much better tone out of it.

So you suggest I spend the money for the bias mod after preamp tubes? I could ask my local amp tech how much he says it would be...

tubes first.

if you have a little extra cash (and plan on keeping this amp for a while) at some point the bias mod makes it a lot better sounding. bias is basically the 'temperature' the tubes are running at, heat them up a little bit more and it shines.

i dont know how much it would cost to get it done, may not be cheap but should cost a whole lot. any tech should be able to do it.

lastly, again don't do the bias mod if you aren't going to be holding on to it for a while.

So does anyone else want to chime in? I'm trying to figure this out before I do anything else.

FYI biasing is for Power Amp tubes not pre amp tubes.

I know. It doesn't really apply to any of the tubes in a 6505 (except for the 6505+ head) because the bias isn't adjustable for the power tubes unless you mod the amp.

it is if you mod it. i stated it was a mod. quite easy to do if you are carefull and know what you are doing.

also i should have specified power tubes in the first post.

Maybe I'll do that at some point, but at the moment I don't entirely trust myself.

Also, tubes or speaker first? I've still got the stock POS Sheffield in there, thinking about a V30 or a K100.

I don't know if this helps but I'm going to swap one of my preamp tubes for a JJ 12AX7 today - I'll let you know if it changes the tone. (It was recommended to me to change the V3 tube to a higher quality one; should improve the tone when the effects loop is used.)

As for speakers vs. tube upgrades, I think a speaker upgrade will probably yield the biggest change in tone. I've got the same amp and plan on keeping it for awhile. My next upgrade will probably be a speaker and then probably change all the tube to JJs.

At this point I'm thinking a combo of Tung Sols and JJ's for the preamp.

Though I am curious as to what Svetlana/SED =C= 12ax7's sound like.

i generally dont replace preamp tubes until they get too microphonic, however if the tubes in there are crap (i had ruby in the peaveys i have had stock), changing the tubes will be a big difference.

speaker makes a pretty big difference, i really like K100's. V30's are more or less the standard. sheffields are terrible IMO.
