5150 tube help
Today I am finally receiving my Peavey 5150 combo from the UPS man. The guy I bought it from packed the tubes (JJs) in a seperate box so I am going to have to put them in myself. This is going to be my first tube amp and I have no clue what I should do, what tube goes where. All I really know right now is that i should have the amp unplugged so I dont electrocute myself.
If anyone knows any site or has a diagram of what I should do, and where I should put each tube, could you please post it?
Thanks for the help in advance.

big tubes go in the big holes, little tubes go in the little holes.

So it doesnt matter which specific plug they go into?
Lol I always thought it was a bit more complicated, serves me right. 
And should i wear gloves or something? Ive had bad experiences with halogen bulbs during tech crew at school, and wasnt sure if tubes were the same way.
i.e. you touch them, the glass pops and can cause some nasty injuries. |

Just don't touch them when they have been powered recently, let them 'drain' before.
It should be pretty safe to touch them I neither the amp or the tubes have had current through them yet, but don't quote me on it.

The big tubes(Power amp) go right on the chasis.. they only fit one way. The little tubes (Preamp) go inside the comparment on the back of the amp.. you will have to take off a panel. They also only go in one way.
Enjoy!

Clean any fingerprints etc. off of the glass with isopropyl alcohol. If the amp was properly biased before it would have been nice for the previous owner to mark which power tube went in which slot when it was tuned. Since they weren't marked you should have it biased. |

Well my 5150 is all tubed up and I fucking love it!
The only issue i had really was the metal coverings on the AX's but I got that fixed in no time (had a bit of trouble pushing them down into the plug). Thanks for the input!

if it's a matched quartet into a 5150(as bls said, fixed bias) it shouldnt be a big deal which power tube goes where.
