Peavey T-40 Club Part 2

Can I join the club?

My first bass was my T-40, picked up in '92 for $50. Today it is essentially derelict however. It caught some damage in a freak stage accident (it was my backup) and I haven't touched it since. It will need some fret repair and I hope the neck is salvageable. Yes, I feel bad about it :(

I'd like to get it back amongst the living. Question: how do you date these things?
 
Here's a teaser.... more coming soon

I haven't looked inside my T-40, but that capacitor isn't on any of the wiring diagrams I've seen.

I've heard of people wiring a capacitor inline with the bridge ground to act as a one-way "safety," which would prevent them from being electrocuted in the event of a major equipment grounding failure. But, I don't think that Hartley Peavey and Chip Todd would have considered that a feature worth including on an otherwise brilliantly-designed instrument...


EDIT: See below. Apparently, those two were even more avant-garde than I thought! :D
 
Why does my T-40 have a capacitor along the bridge ground wire to the output jack? Is that standard stuff? I've got some minor grounding issues and I'm wondering, what the heck?

Peavey did use a capacitor in series with the bridge ground as a "safety" feature for a while. You can take it out of the circuit and have a hard ground. Doing so will only increase the shock hazard to the same level as 99.99999% of all other electric guitars/basses that have ever been built.

So I did a little modification in hopes of defeating some clipping in the pickup.

Based on the suggestion from the T40 forum I clipped the red wires from the pickups to the tone pots. This disengaged the roll-off humbucker feature, puts both pups in HB mode (I think) and adds lots of top end sparkle. Still struggling with the clipping, but I've lowered the pickups significantly and that seems to help.
