I have a Xin SuperMini 3 that's got a loose connection somewhere: if the output cable isn't inserted just right, then I pick up static and radio signals. This started happening after I tripped over my headphone cable five years ago, and the amp has laid dormant since then until I recently started testing it again. It looks to me like something broke off on the output jack. Dr. Xin is, as ever, absent, so there's no way I'll get this repaired by him. Does anyone know what kind of 3.5" jacks he used in his amps? If I replace this one, I'm sure the amp will work as new once again. 
 
Thanks, 
Jack

Send a PM to HiFlight, he may be able to assist.

Thanks, I'll try that. I've been playing around with the jack this evening and I've got it working (the issue is that the ground in the jack wasn't firmly in contact with the cable plug), but I'd love to fix this for good (I'm hoping to sell the amp, I find it makes only minimal difference to sound quality with either my computer or my ipod).

Glad it is working better, what op-amps are you using on the Supermini?

One omamp is an AD8397, the other is bypassed. Part of my problem is that I have pretty poor hearing, so I often just can't hear subtle differences all that well.

Depending on whether you use the voltage boost feature or not you could use the AD8656 or the AD8616. I personally prefer the AD8656 but others differ. Good luck.
