new 5150 III schematic

[enrique_venere]

Hi guys I`m new here and to be honest I`m looking for someone that have this schematic ...
I imagine that this new one it`s very similar with the 5150 II but the idea of having 3 channels and the sound that this new one have excites me a lot...
I love specially the sound of Ed, that`s why I have one peavey wolfgang and a project of frankstrat here with me, and would like to try do this amp...
I'm trying to get ahead but I don`t find this schematics...
Thank you ..
Ps: sorry about my English ...

Thank you man I don`t believe that someone have already post this schematics but to be honest I can't read the values!!!
I will try to do something to read ...
Thanks for posting though!!!

try pm'ing good guest, who posted the schematics. he may point you in the right direction

I agree with u. I don`t know exactly is but they are different and I would like to konw What!!!
I believe that essentially is the same thing but ...
Only looking the schematics to know ...

Yes sure, I will...
Thank you again man ...

I recently got a 5150 III and the schematics came with it, so did a quick scan of them this morning for you guys. I'd be really interested to hear any comments on the circuit. The image limit here is 800 pixels so I posted the 3 schematic drawings up at high-res here:

Also please let me know if I'm not supposed to be posting this kind of thing here and I'll remove them right away.

Thanks.

[spaceace76]

it's totally fine to post them. the schematic even has the footswitch

this is pretty awesome. if i wasn't knee deep in restoring a sound city L120 i'd be digging through this thing...

[jimification]

Thanks spaceace. I added the layout diagrams and made some overlays too (same page as above).

You can find it here along with a bunch of others...

I see some zeners used..why ??? I just cascaded the front end of a handwired last night..added a type 2 PPIMV nails the VH tone. so does the standard 100 metro kit with the same mods.

[videocat23]

the zeners are most likely for noise reduction on the p/s circuits. this combined with some regulators makes for a cheap, clean, more reliable power supply in most cases.

[jerrydyer]

thats a signal bounding technique. The noise reduction (high end hiss reduction) is a side effect.

[Good Guest]

Yep for sure ...that's exactly what's going on (signal bounding). The signal is being bounded or clamped to only reach a certain voltage much how a regulator works.

Those who build the jose master w/zeners notice the same thing ....they turn up the master it gets bounded and clamped and nothing appears to happen once it reachs the threshold.

I speculated once that maybe the jose master was a design jose used for the opt primary mod as it would limit the voltage going to the poweramp. Thereby saving the opt.


Dr Dirty notices the low noise effect of the bounding technique in the other 5150 lll thread also.

Anyways I just have to bump this thread as there are many people pming looking for the evh5150lll schematic.
