I've never used tri state before probably because my experience with PTS in
the past has been less than satisfactory; I got tired of repairing
"repaired" modules that were sent to me.
I may give them a shot if enough people here know and like them.
Any opinions on Tri State out there???

TriState module may be a quicker repair,if they have one in stock.
I was quite busy a couple of weeks ago,and sent a PTV84x module to them for
repair.
Although if I'd have had a schematic,I would have tried to get some of that
money for myself :-)
