V3207 chip

[Popnfreshbass]

I know there is a chip shortage right now. But if anyone knows where I could get one, or had an extra to sell, let me know!

I’m thinking about picking up some of the affordable pedals on Amazon. If they stink, a bunch of them have bucket brigade chips in them I could salvage

I ordered one from banzai and they said they were in stock. Turns out they were back ordered. So all I’ve done is preorder one when they come back in stock.

I have some...PM me your address

That happened to me too. It so annoying.

Ya. Bit of a bait and switch. I’ve only mad the one order from them. They may have sent me a fake 2n6027 too. Waiting on a mouser order to confirm

Is there any decent way of testing mn3207s short of dropping them into the circuit? I have some but I'm not sure if they're fake

I just ordered a batch of those on eBay. I had a ceasar already built, so i took the v3207 out and then tested each mn3207. Only about half of them worked, but I got 10 of them on eBay for about 8 bucks from a seller in Hong Kong. 50% is not great. But I'll take it

But if I hadn't had a pedal that I knew worked, It would have been a pain testing them

I plan on using my newly acquired pork barrel to test the batch I have coming.

Also, I was reading some of @temol 's posts at DIYSB from a few years back regarding a cabsim he was building. I believe this was the test circuit? Maybe he can shed some light.

 

[temol]

Unfortunately I do not remember exactly how I tested the chips. The circuit above is not a test circuit. It's quite possible that I've breadboarded a circuit from the MN3207 datasheet (Echo effect) or a circiut from this thread.

Yeah, I actually looked at it after posting it (get your head in the game Tim). I may try that echo circuit on BB. Thank you!

Almost broke my eyes trying to read Scruffie's schematic. Traced it but there might be errors. Haven't breadboarded it yet - this was enough adventure on this front for one day. Sourced from this DIYSB post from Scruffie. Should produce a low fi slap back.

[schematic was revised after the next message]

The only thing I see is the bias pot pinout is wrong maybe.

Yup, the same thing happened to me too. I ended up asking them switch it for the MN3207, but now I am worried it's gonna be a fake.

Seems like a few people on here have had bad experiences with banzais products.

Thre 2n6027 transistor in the same order I placed was a dud/fake. So yes buyer beware of banzai.

The Coolaudio V3207 is in very short supply right now, but we were able to get a limited quantity in stock today.

Thanks for the tip!
