Aoyue 862A+ Help.
 

Looking for a picture of the main psu panel.
the reason I picked one up sometimes it seems go ok other times
it just shuts down.
opened it up and everything looks fine apart from this strange item
theres a wire coming from the bottom of the air ball at the back and its been soldered direct onto a 3 pin vt transistor .so don't really know if
this is normal or its something to do with my fault.
be obliged for anyhelp thanks.
sorry on my heading it should say model number Aoyue 852A+
Hope Iam Posting In The Correct Section.

i had same problem and i solve with :
i resolder ic pic 8+ 8 pins ( in my case model 853D ) and now working fine ..with the machine vibrations leads to the breaking of the welds.
