Sometimes a friend will call with a favor, sometimes it's a really big and heavy favor.  EMT 140

Another favor - I'm not an electronic accordion tech by trade - but here's the IORIO Accorgan.  Needed a new voice to replace a dead one.  Plus a lot of cleaning and TLC.  Worth it??

The rare and fantastic (when working) AKG BX20.  Impossible to find parts for the pickup assembly (I have looked into custom winding them - no luck yet), often these units wind up being used in mono.  This was the case with this sad one.

This Roland SRE-555 tape echo had very badly worn heads - see in the above "before" pics.

Since I owned this unit, I thought I would save the expense of sending all 6 heads out for relapping and try it myself.  The Nortronics manual on relapping is very complete.  I did the procedure in my kitchen sink. See how they turned out below!  Pretty perfect!
