It appears that the distributors who carried all Excelitas Vactrols are now claiming they are either out of stock with "no known leadtime", or they are no longer being manufactured.

I need some. Does anyone here in DIY have at least 100-200 pcs of extras they can sell to us?

If you have 5C2/2 or 5C4/2 instead, we can use them.

I made a lifetime buy a little while ago and unfortunately I don't have enough to spare. There's been some talk about these finally reaching EOL status so there was a fairly large group buy facilitated by a member a little while ago. The only option may be to go with a cool audio clone but they only make the single 5c3 clone.

A more long term solution is to get the files from this thread and 3D print your own.

I don't need a pretty enclosure, thanks. Can always improvise with heatshrink tubing or some other means.

The most difficult part of making one's own Vactrol is getting two LDRs that track together. It requires building a testing jig. Yes, the Chinese-made single LDRs are small and cheap. But the hand-labor of matching them is not. The dual-element /2 Vactrols were really good at tracking together and DIYing an equivalent is a PITA. And I have yet to find a current-day reliable source for a dual LDR.

Same goes for Silonex couplers--random samples are all over the place and they have to be matched. And they have much slower decay times.

For now I just need enough dual vactrols to finish up some leftover PC boards. After that the boards can be modified to take something else, whatever.

Give these guys a call? Their website says they have 5C2/2s in stock for a lower price than the 5C3/2s as well.

Thanks for the link, I ordered a few, for this price it's worth a try.

Amazing - but I tried to check out and shipping to me in London for x10 vactrols was nearly $200!! woah waah

Would anyone that has ordered a load of 5C3/2's by chance be willing to send me x5-10 from your stock just via regular post and I can cover all costs and pay a handling charge for your trouble? I'd be really indebted - please PM me if so - thanks.

Just heard back from Anita at Allied Electronics. She says:

Quote:
Factory came back that this part has a 1k pc order min now and this part will be obsoleted soon, did you want me to get a quote for 1k pcs? Let me know!


Which is "interesting" because everyone else claims they have been discontinued. Permanently.

Would anyone be interested in another group purchase? Or shall we wait for the actual Chinese manufacturer to start selling them directly on eBay or Alibaba? That could happen....

Would be mega interested in a group buy - yes please!!

Group buy sounds like a plan. I missed out on the last one.

note that those chinese ones are single vactrols though, those aren't discontinued (yet) - Coolaudio makes VTL5C3 for example. it's the dual matched ones that are becoming impossible to find.

I bought a big bunch of those Chinese ones from the link a while ago, and it seems they're all over the place. Fun for creative use or whenever "just put a vactrol there and try out which one sounds cool" is needed but not very useful if you need a spec that's guaranteed in any way.
