Tube Swap - how would you do it?

I can't believe how bad this looks in Grumpy's pics. It seems like whomever soldered this had poor vision, shaky hands, and more poor vision!!!!

I know, right. It's really not on for a manufacturer to be putting this type work out into the market, & where TF was the Quality Control guy. I'd be asking if they are getting stoned at work Mr Grumpy (I'm betting they are). Cheers
 
Get ya a nice USA MADE PEAVEY TUBE amp Grump---send me your CC # and shipping address ---Ill hook you up ;)

I know of a very nice Triumph 60 -- right here in the hood ;)

Peavey Triumph Ultra 60 1x12" combo tube amp with original footswitch.
Three channels: clean, crunch, and ultra (ultra gain)
60 watts
Tubes:
(2) 6L6 power/output
(4) 12ax7
(1) 12at7

This is a four stage hi-gain stage amplifier.
The three channels are kind of like clean/fender, crunch/marshal, and ultra/mesa all in one amp for lack of better words...

The heater wiring that is attached to pin 4 and simultaneously connects to pin 5 is absolutely horrid.

Yes, it is. The more I look/think about it, the more I dislike it.

The connection to pin 7 is another messy abortion too, but much easier to rectify.

Yes, that's true.

Unless you can make sure that there is not any bare wires or solder, at pins 4 & 5, that are straying over and contacting the sockets mounting hardware, I WOULD NOT TURN THIS AMP ON TILL THIS AREA IS FIXED!

Funnily enough, I lay down in bed last night, looked at the amp and unplugged it from the wall - the 4/5 looks like a fire hazard...

BTW, the blue thingy attached to pins 1 & 3 is a 100 pF ceramic capacitor.

:D

You did the right thing leaving it against the chassis.

I just wanna check that (because I'm severely lacking knowledge here) - that capacitor should be resting on the chassis?

If I were in your shoes I would definitely be sending the manufacturer that V1 socket pic with a WTF mate type accompanying rant.

I did. I sent a nice and polite note with the picture. It'll be interesting to see what they say.

Me too. I don't expect that from this manufacturer, and it's not inline with the point to point work on the main board. At the weekend, when I have a go at this work (although, I'm pretty sure I threw all/most of my soldering gear away long ago...), I wanna check the EL84 soldering because if it's perfect then I wonder if Thomann did this work on an amp that was somehow damaged? If the EL84 has a similar level of soldering then I'll have to think the manufacturer needs to up their QC. Maybe I'm just making excuses for a manufacturer who should be above this level of shoddiness...

Just down "near" the chassis will be fine. The leads are insulated so will be fine. I only say to position it near the chassis as it appears to have been soldered in that position, so best not to bend it around.
I hadn't thought that the bad socket wiring/soldering job may have resulted from someone repairing damage, but it's entirely possible, especially considering that the shield top doesn't seem to fit on straight. They normally sit straight up, like this

This is the same type (Belton) socket as fitted to your amp & has a tube in it.
Is the power tube socket of this same type? The Belton 9 pin sockets are available with or without the shielding & it's uncommon for a manucturer to use different type sockets in an amp with only 9 pin sockets.

It all looks the same. Next time I open the amp up (the weekend), I'll double check.
