Mods / Re: Dunlop Univibe not fast enough!
« Last post by harpplayer on Today at 08:18:16 AM »
Oh, the 22 meg bias resistor is actually 72k, that was a mistake on the schematic, but I donīt think it is related to the speed anyway.

Mods / Dunlop Univibe not fast enough!
« Last post by harpplayer on Today at 08:16:23 AM »
Hi there! Quick question. I have a Dunlop Uni-vibe UV1 that the fastest setting is just not fast enough. Actually, it is not really fast at all, and Iīd like more helicopter like settings.

Is there a way to mod it? I thought it would be something as simple as with the CE-2, but clearly it is different. Here is the schematic portion I found. Changing the 92k resistor would only limit the pot action, whereas changing the pot to something like 100k would change the resulting value, but I donīt think this would make it any faster, only more control over the slow settings.

Anyways, any ideas are really appreciated!

Tks!

Storyboardist, a member here, has an incredible blogsite with more layouts than you can shake a stick at.

Also known as "perfboard" -- Jon Patton's layouts largely use this, as does a lot of the Run Off Groove stuff.

There are dozens of us! Dozens!

Consider myself enlightened.

I think I saw a clock with tubes like that at a local music store. I thought that was wicked cool, although if I had to splurge money on a music themed appliance I'd get one of those Marshall fridges.

Open Discussion / Source for Panasonic ECQ series N.O.S. capacitors?
« Last post by Gui113m on Today at 03:36:37 AM »
Hi!

I want to restock my Panasonic ECQ capacitor drawers. I'm aware that they are now discontinued but I hope they are still available somewhere as New Old Stock.

Looks like ECQ-V aren't that hard to find (values 100N and up) but I'm having hard time finding lower values (ECQ-B?). The two values I need are 390pf and 820pf.

Do you guys know where I can get these low value Panasonic caps?

Many thanks!

Clock Pulse, usually (assuming we're talking BBDs?)

When you look at data sheets for ic's some have pins labelled cp1 cp2, what are these?

Plenty of stuff can be made with perfboard, even vero layouts if you're willing to make all the connections. Just be careful, it can be a little more prone to pad lifting (may just be my experience with cheap materials, but worth being careful either way)

This is what the usual vero stuff looks like. Also known as Stripboard:

I need to re-check those voltages in the PB. I think I have a couple written down incorrectly. I would hold off before doing anything else (should be able to check in the morning).

Me and my sanity will be standing by!   :o
