How many swedes does it take to screw in a light bulb?
Just one, but don't count on it ending up in the right socket.... :rollover

Seriously, looking forward to hearing the demo.
 
Well, if he posts a video with his underwear on his head, we'll know why.

In all seriousness, I hope that that resistor is the only thing that went bye-bye.

Finally, I've heard bad things about the Illinois caps (marked "ic"). Depending on the age of the amp, you may consider having those replaced when the amp is serviced.

Sorry about your misfortunes with the amp, but hopefully it should be relatively painless to have it fixed.

You heard right tung. I got a terrific book on tube amps and the author despises ICs as they're pure garbage (in his words) and says replace all of 'em and as a result the amp will sound 10x better.

I hope all the best for you Robert.

EDIT: now that the posts are updated I had thought that Robert switched the tubes.

Glad to hear it's all good now,and that is an easy mistake to make.Your a good man to fess up to it.Sumi:D

I agree with Sumi. You're a good sport, Robert, and you may have just insured that the rest of us never make the same mistake. So at least something positive may come of it.

I won't ask how much $$ this amp has run you.

Oh, I almost forgot to poke fun at you...

While he doesn't badmouth them, it's interesting to see that Bill Machrone had replaced the IC filter cap in the first filter stage of his Pro Junior in that photo I posted earlier in this thread (repeated below). He states that the two Xicon caps he substituted "....have lower ESR (equivalent series resistance) and better ripple rejection." But he left the IC caps in the 2nd and 3rd filter stages, so he must not consider them "pure garbage".

BTW, his Pro Junior is a newer version (2006) and had a 47 uf IC cap in that first filter stage (Robert's has two 22 uf IC's there). Machrone replaced it with two Xicon 47 uf's to cut the voltage ripple in half.

All is good - I got the amp back today. It sounds great!

What was the problem? I am embarrassed to say - I put the power tubes into the preamp tube sockets, and vice versa... go ahead, slap me twice :thwap :spank :spank

Live and learn...


Oops :thwap

I'm glad neither the OT or PT were taken out. Live and learn I guess. :dude

I can't see nuthin'. Some kinda exxplloosion blinded me!!!

That's why I were prescription safety glasses when I work on amps. I haven't had anything blow up on me yet (knocks on wood.) I did flip molten solder up in my face and missed my eyeball (was not wearing safety glasses at the time) and it made a believer out of me. I never work in my shop without my safety glasses.
 
I have never done any amph work, but good thoughts. I always wear eye protection, for mountain biking, (and road), skiing, mowing the lawn and string trimming, cutting with the chop/table/worm drive saw, etc.
