what i did was, turned the amp on, playing though it while unplugging the AC cord.... and letting the sound fade out.
opened it up and took a voltmeter to the caps...... nothing. so it was safe.
replaced R1 with a 1M. holy shit. took the blanket off the amp. tons louded now.
briefly tried a master volume knob in place of R5. hated it. if the power tube isn't distorting, the amp has no character.
put R5 back in, buttoned it up and i'm done.
i'll find a proper metal film resistor for R1 at some point. right now there's just a carbon one in there. good enough for now.
i'm convinced that the key to this amp is the cabinet it's going through. which is why the combos sound like crap in comparison.
Yeah R1 to 1M was nice at first, but it wasn't my thing. I tried others and am back to the stock 68k.
I agree on the cabinet. I'll be playing thru a vintage 30 and a G12H-30 cabinet from avatar (which should be in tomorrow).
Glad you gave it a shot though!

Wow I might have to spend some more money. Get another Junior and find me a circuit with a single 6v6. This could be way way way cool.

That's what I want, a single or dual 6v6 power tube layout and an EF86 preamp all with great input and output transformers.
I agree this could be way cool. Get a couple Valve Juniors. Turn one into a 6v6 circuit, another into a 6L6 circuit, and so on. Have them all stacked up at the studio, and have add it. And not have to spend a ton!!!

i'm tempted right now to sell my blues jr, buying another valve junior head and a stereo 2x12 cabinet.
the valve sounds better than the blues.
Friend of mine is putting a princeton circuit in his valve junior. Ephiphone did a great great job!

Here is the link to the set up. I put the Dano in there to help block out the avatar logo some (don't ask me why, I'm off in the head some). Sorry about the smudges on the guitar (didn't realize it was that bad!) Should of rotated the picture guys/ gals, I'm sorry about that!
Those with out myspace accounts, PM me and I'll email it to you if you like.
The cabinet is open back 2x12, with a G12H-30 and a vintage 30 (16 ohm each in parallel) (for $288 it's a killer deal). Sounding killer. Head is a little modded (see earlier posts). The Dano is cheap but it's me. I'm a bass player, who just rights some stuff on guitar, nothing major, and that guitar is my baby.

Finally have a cabinet for the Junior. Honestly I think there is just way to much read in this. Not to mention that cabinet is probably going to be way to small, and have a crappy speaker in it

No clue, friend of mine just sent the link, he didn't have any information.
I'm going thru a bad A$$ avatar 2x12, with a G12H-30 and a vintage 30. Nice and big.

First "band" I was in when I was getting started. The guitar player was playing his Peavey Classic 50 thru a single 15 tweed peavey cabinet. And he would have the bass knob cranked. Back then I only had a Peavey TKO 115 80 watt solid state bass amp. I'd have that thing cranked, and the high's cranked just so I could slightly sort of here what I was playing.
Excuse me Mr. Guitar player, would you mind turning back those lows so that I could possible here what I was doing?

Ha ha, I used to rock one of those TKO's too in a jazz band when I first started playing bass. I only had a guitar wah pedal but it was still good fun on the high notes for solos.
Sometimes the 15" guitar speakers can be down right shrill on the highs. I'd definately have to have a beam blocker.
I wonder what a 4x10 Ampeg HLF cab would sound like on guitar.
My Girlfriend said to me..."How many guitars do you need?" and I replied...."How many pairs of shoes do you need?" She got really quiet.

You know Peavey actually had a good preamp section in that combo. My buddy's studio has the rack mount version of that pre-amp, and I'll admit it. I've used it more than once. Heck if we are jamming over there, I usually don't bother brining anything, I'll just plug direct into that.
As for what would a guitar amp would sound like going thru that cabinet. I could find out for you. I have that cabinet. I just have to replace a speaker in it (I'll need a little time for that one, I'm on a allowance on what I'm allowed to spend, the wife runs the show).

oh yeah the amp and preamp was solid, my problem was the speaker since it was ragged to death being a school unit. When we jammed I'd just pull down the 12" peavey PA speakers and that was sufficient.
That bass cab is one of my favorites of all time, I hope it sounds cool with the JR if you get a chance to replace the speaker. Does it need reconing or a new voice coil?

Here is the latest. The big problem with doing so many changes in a row (even though hearing what they did each time) is that you ears get so used to things, and you don't notice it. The amp days later when plugging it back in seems way to bright for my needs. yesterday went back in and did the following:
R1: back to the stock 68K
C3: down to 2.2 uF
R9: down to 1K
Now I have my tight punch back, not to bright and most of the flabbiness out of the low end when cranked. A little of it is still their, but I'm at a happy medium. I won't use the amp on kill most of the time any ways, usually around 1 to 3 oclock.
I didn't get around to doing sound samples on thursday, we were to busy trying to get a organ track down. Hopefully this thursday I'll be able to jump on some tracks.
Here is the latest mods. Noticed when I'd get into humbucker pick-up guitars, that there was some still some flabbiness on the low end starting around 3 oclock.
C3 & C4 are now up to 4.7 uF
I have a Jpeg of my schematic changes if anyone is interested.

oh I don't know, it's probably just as easy to buy a replacement, it's just a bit cheaper I'd think to get it repaired depending on the problem.
Yeah that is true. And depending on the speaker. If its some $200 green back, I'd be getting fixed. But if its a $65 Eminence, then that isn't really worth the hassle etc...
