Kind of obscure thing , but hopeing someone might know.
I just picked up what looks to be an early to mid '80's JCM 800 Cabinet . Got a fairly good deal on it- one ninety shipped.
The Grillcloth looks like a light straw brown color, and from waht ive been able to determine from looking around the web, it looks as if this was a cabinet from a certain batch of Marshalls from that particular time where the black faded to a light straw brown.
It looks cool- kind of like an old late 60's brown basketweave.I n fact, I am going to get a Plexi Logo and make a replica of sorts.Noone will know i guess.
Anyhoo, I have a *question which is about the speaker *screws in the cabinet. They are all old checkerbaord style Whitworth Flathead screws. I was under the mistaken impression that all JCM's all used Phillips, as are usually found on JCM800's and ater cabinets, but i guess there must have been some overlap from the Checkerboard era for a good while even into the mid '80's where *where they used up the inventory of remaining flatheads?
Also, does anyone know the specific thread size on the Whitworth panhead screws, as I am missing two flatheads frm the cabinet and as I understand it, the originals are scarce.
Thanks again everybody , you've been a great help and I do appreciate it.
Here it is;
