Allright, they sent me a schematic, no parts list so doesn't do any good... It worked fine when I recived it, all new sprague caps, etc.. was reworked. Then it started haveing problems when switched on.. 1.It has a three way on-off-on switch- the schematic does not show if it has an internal breaker. 2. The two main capacitors- one checks out, the other shorts out...but I have no part number and you try calling Gibson and see what they say...LOL! "We don't make them any more..." Anyone know what the cap and switch are and where to purchase them... I'd replace both large caps....I don't see a number on the liners.... Thank you....
