No More CDE PVC Caps

[RJ Guitars]

I have been looking for replacement stock on the CDE PVC601 0.1uF caps for Wreck builds and not finding much these days. Maybe somebody would like to sell me 100 of them? In case they don't, has anyone worked with some of the other Film and Foil coupling caps and come up with a good alternative for an Express build? I'm not sure what JM is using in the new Wrecks but I would expect he has to have a reliable supply of something more modern?

As if to add insult to injury, I've been waiting nearly a month for some new Sozo stock to come in.

Anybody have any suggestions for the future?

thanks,

rj

what's the difference between the pvc and the wmf/wmc?

it looks like the pcv is an orange drop type casing but they are all film/foil?

Hi RJ,

I found this link for PVC601 at onlinecomponents but the lead time is 8 weeks:
http://www.onlinecomponents.com/mallory ... p=11711530

They also have the PVC6222 with 81 pieces ready to ship when I looked:
http://www.onlinecomponents.com/mallory ... p=11711561

Unfortunately they don't have the PVC6122 and it is listed as discontinued:
http://www.onlinecomponents.com/mallory ... p=11711543

I don't know if you got my untimely email enquiring about PVC caps yesterday, but would still be interested in buying a set from you if you get some in.

Hope this helps,
Rick

Oops just noticed that onlinecomponents was on the BOM already for these caps .

PLC Center claim to be able to supply them. The shipping cost to the UK was crazy but probably more reasonable within the US:

I've been meaning to try these CDE DMT series, they're polyester film and foil. http://www.mouser.com/Passive-Component ... mt&FS=True But go figure the .1's are priced in the stratosphere. 22's and 47's seem to be quite reasonable.

What is wrong with the vishay 6ps cap?

[RJ Guitars]

I think there are numerous options for the caps, but the CDE/Mallory set has this incredible history and consistency in the making of the Express and Liverpool builds.

I did finally locate 250 more PVC612 caps but the price is crazy... and I bought them anyway. I really want to be able to hold on to the known formula as the bench mark for all the great experimenting going on out there.

I've also order a few other choices so that the comparisons can be made and I expect some great sounding Wreckish amps to emerge that could rival a Traditional build... I hope to build one myself in fact.

I'll post results as they show up and look for the occasional cheap price on the PVC caps - I know there are thousands out there, just gotta know how to find them.

Not sure if this is equivalent to the PVC 612 caps and whether you need an equivalent specifically.
But I get all my caps from this dude and his stuff is excellent. Fast shipping too

Yes on the PVC612 the 6 is for 600volts, the 1 is the number of zero's and the 2 is the value - so you get .02 @ 600 volts. It's useful in the Express build and they can still be found in reasonable quantities for a decent price. Where I got stuck was on the 601 value... they are not so common.

Just Radios has a 630 volt "orange dip" capacitor - the 630 rating is more common these days but that isn't the same as the nostalgic Trainwreck PVC caps... it might sound as good, who knows? It would be worth making up an Express and doing the A-B test but you need the ears and fingers of Geetarplayer to really give it a fair test.

I have used Solen caps in other builds and they destroyed the mallory 150's, granted the mallory 150"s are not great. The problem with Solen is the lowest value available is .1uF

solen makes caps in all value ranges.

Plenty of other caps out there that sound great in wrecks. No need to panic.

For me the options make up the important point of this thread. For the purist I have found enough product to keep the tradition alive for quite a while. On the other hand, for the guy that wants to build a great sounding amp but isn't feeling nostalgic about it, the use of something modern and lower cost is wide open and I think it's fair to say you can expect to create a great sounding Wreckish amp.

I did score a triple handful of PVC101 caps - 0.1uF @ 100 volts. I am using these to tap off of the speaker output for the presence circuit. For an Express or a Liverpool build this will save 1/3 of the 600V caps for the critical spots they are needed.

Thanks for all the help on this... I expect we'll see these show up slowly as long as the demand is steady. For those not familiar with the big electronics clearing houses when they say 8 weeks delivery time that usually means that they expect another production run or need some extra time to dig for a product. For the PVC's I did talk to Mallory twice and they indicated that these were absolutely out of production but they had plenty of newer products for me to consider. It was a bit of a fun adventure to scour the vendors while looking for these. There is one guy out there with 19 of them available. He started by asking $9 each for them but as each of the big outfits called and asked for this part number his price went up. The final quote of the day that I got back from someone who had contacted the same guy said his price for these same caps was $26 each... that kind of nostalgia is a bit too pricey for my blood. So in some self destructive way by making dozens of phone calls and web inquiries I was able to artificially escalate the price well beyond reason... of course that guy still has his 19 caps on the shelf.

I've continued the quest for these... I had to quit offering to sell any of the original PVC caps in bulk and offer them only with an amp package so I could keep the the critical components in the amp parts packages as authentic as possible.

I recently found some more stock and as you can see they all have some similarities. Occasionally I find a few chocolate drop caps that claim the PVC601 designation. Attached is a photo of the iterations of 0.1uF 600V polyester caps I've seen along the way. The question is: Are they equivalent?
