Eminence CV-75 speaker ?

I recently installed one of these in my homemade JCM800 1x12 combo. Absolutely love this speaker. Has anyone else out there tried em?

Re: Hot Rod Plexi 100w number four

That's a hell of a collection of builds. Out of all of them what was the best sounding or had the most surprising tone upon startup?

Really nice.

I had that same issue with my bassman 50. Had to seporate the two boards :)

Re: Trouble shooting scratchy pot on JCM800 style build

Looks like a 2203. Check all resistor values that go to V1. Try running the volume pot ground to the back of the pot instead of the buss wire. Try seporating the signal wires that go to V1. Used individual shielded wire .

Re: Master volume mod

Stevem,

So
Your tying the plates of the phase inverter and output tube together with a 220k resistor ?

Master volume mod

Here is a mod I've done to a few amps. Is your amp so loud that you never turn it up past half way on the master volume? This mod will give you more control over your master volume from 0 to 6. Do the mod I posted and now when your amp is all the way up it's it's actually turned up to 6 ( half way)....

Re: fender Bassman 50 to #102 Robben Ford Dumble amp

Like this? If you want Rock and no PAB, almost. You need to connect the top of the bass pot to the bottom of the treble pot. here is the output section. That looks fine. Just Rock for this guy:} like this? [IMG:768:1024]http://i1051.photobucket.com/albums/s430/baddog01/93A0B266-1EFE-4C79-BD8A-C4610...

That does make sense. Plus id have more room in the chassis under the P/T for the filter section....
