howard	MXR Stereo Chorus Hello Friends I'm hoping you can lend some advice..I just got a '70's MXR Stereo Chorus, in non-operating condition..I was told there was a chip that fried on these and this may be why its dead. Any thoughts or advice? I'd appreciate any assistance you can offer! Thanks for your attention. Feel free to email me at: lizardluv@hotmail.com. PEACE, Howard

CJ Landry	I just repaired one of those and it was a power problem. Check the regulator and zeners for proper operation then check back. This can be done by confirming +/-V on pins 4 and pins 8 of any 4558. CJ Landry

Padelis	Hi, CJ Landry i was wondering if you could send me a schematic of the MXR Stereo Chorus or any other unit with MN3011 and MN3101.By the way do you know were i can find the datasheets of BBDs.I remember that there was a site with about 15 datasheets. Thanx.

CJ Landry	The BBD site is at this link.http://balassant.sote.hu/madchem/el/bbd.html Where are you located? My copy of the Stereo chorus is not real good. A fax copy may not be legible. I will try a scan and I can e-mail it. Your unit with the MN3011. That is a reissue unit isn't it? CJ

I am from Greece.Here in Greece there are just 3 people who build effects and amps,2 of my friends and me.Their age 50 years old and i am just 16.I have built so far about 15 tube preamps and 3 100Watt tube amps.Also I have built a reverb/echo unit 5 years ago.Thats where i got from the chips.They are original Matsushita and i want to built a chhorus unit using them and i have heard that MXR stereo chorus is great but i dont know if it uses MN3011 so could you plz tell if there is any schematic using MN3011?????????

Thanx in advance,

You were ELEVEN? Man, I think I was still learning how to do long division at that point in my life. Congrats! You will go far.

I'm 10 years older and I still won't touch anything connected to an AC mains line.

Keep up the good work Padelis!
