polystyrene cap in xpress...Wow!

[KellyBass]

Just got a few CRL 500pf 630v polystyrene caps in the mail the other day (for another project) and thought I might toss one in one of my expresses in the 500pf slot between the plate on v1a and the treble pot. I replaced a silver mica cap.

Wow! I gotta tell ya...I'm very impressed! It took a TON of nasty edge off this amp and everything overall seems much more civilized. I'm gonna stock up on these in a lot of different values...

Keep it quiet on the Polystyrenes. They don't make them anymore and I don't want to pay big bucks for them either. they have been my secret weapon for years. Watch the heat when soldering , they are a bit delicate.

Ah, Gotcha...mum's the word...how do I delete my post?

[billyz]

Well, we could try to corner the market first .

Sounds like a plan!

From me and BillyZ!


"high end polystyrene caps made from only the finest virgin polystyrene as used by Slash and Brad Paisley" only $10.00 each

Just kidding

I got mine from Watts at turretboards.com but I see there's some on ebay...

I'm sold on em' now!!!

[billyz]

I have a large stash so I have not bought any in a while. But, I got the last batch off Ebay. I think most of mine are Phillips .

[Structo]

Has anybody used the larger values for coupling caps?

I see most of the ones available are not very large in values.

[billyz]

The larger ones get pretty expensive. Conrad Johnson used them and they sound fantastic. I figured for guitar work they were overkill. But then again, I would love to hear an Amp done up with them.

[ampgeek]

In regard to larger values, aren't the Orange Drop PS series polystyrene?

[KellyBass]

Seems like I remember seeing a datasheet on PS orange drops...and they are Polyester and Polypropylene Film...but I could be trippin'

[billyz]

Orange drops are Polyester or Polypropylene. I forget which is which. I know from ancient experiments I thought the Polypropylene's were too Sterile( subjective I know ) for my guitar amps.

[Firestorm]

Read something good about certain polycarbonate caps somewhere. Maybe we should start winding our own ...

[ampgeek]

Yep..my bad. Just did a quick perusing and the PS series up to 1000V are polyester.

I was the one drinking the cool-aid!!

Sorry for the confusion,
