What's this cap?

The Orange Drop with the Mesa writing. Polypropylene or polyester? This is from a Mark V.

Will bet that's a Mesa branded 715P. Polypropylene.

Still have 716P's in your Express? I have a set of 6PS's coming in today. I'll try them out. It's been almost a year with the 716P's in my Express.

I was just curious about what Boogie uses.

I've seen 225P polyesters in Boogies too but I think that one looks like the 716P profile. Maybe somebody'll show up with the facts, not guesswork.

Yep, still have 716P in my PCB Express. I've got a set of Mallory PVCs for my real-deal Express and Liverpool builds though.

Cool. Got them in except for the presence. It got rid of the splattyness in the high end that my amp had. It really softened up the top end.
