The trem is working, and is AMAZING Vic. It's one of those output tube bias ones?
All things point to it being a '63. I don't know about grill cloth though, maybe you could give me a better answer. If it is maroon that has faded, it could be a transitional between '62 and '63, this would actually be very likely as it looks like it is running 5881s... Haven't taken the back off to take a good look yet, don't plan to until I am on holiday ?
Sadly I haven't had the greatest experiences with Karel and will be looking offshore for accurate replacements.
According to this source, the head had wheat colour grill cloth (62-63). Yours looks to be faded maroon ? The circuit order was 6G9, 6G9-A, 6G9-B , so yes, that could point to a '63

All you need to do is to unscrew the back panel and peep to the right...you'll see the tube chart there ?
