Is it hard to change a 6505+ lead channel to 5150 specs? Could any half ass tech do it? What would need to be changed?

I can't answer that. I have no idea of your abilities. If you want to try it the best thing to do is contact Peavey and get the schematics for both. Compare them and you'll see about 10 or 11 differences between them. There are changes that need to be made on the preamp circuit board and the main circuit board. You have to basically gut the amp to do the mods.
There's some info floating around the web that is incorrect. The stuff on the web says there's only 3 or 4 things that are different. This is not true.

Thanks for the reply. I wasn't going to do it myself, but I really didn't want to ship. I was just thinking of getting a local tech to do it. I read somewhere that there was only a couple of parts that needed to be changed. Thanks for clearing that up.

A local tech should have no problem figuring it out. It's just a matter of looking at both schematics and changing things on the 5150II to be like the original.

i was told this was posted on the peavey forum a while back.im not sure how accurate it is.you would have to ask jerry,he would know.
C2 from a .001/630V cap to a .022/400V cap
C17 from 470pF back to .0022uF,
add a 470K resistor in parallel with C17

There's much more than that different between the 2 amps. Changing those things will help, but it's not the complete mod.

I have the prices on my site 5150II/6505+ Mods There are about 11 changes that have to be made for the complete mod. The main circuit board and preamp board have to come out of the amp to do it right. Some shops tack the parts on and don't remove the boards which is the hack way to do it. They charge HUGE money and then take short cuts. If you get the schematics from Peavey you can compare them and see the circuit differences. Jerry |
