1969 Marshall JMP amp circuit board,
Does anyone know what size nuts are used for the circuit board ( nuts) ?
And the Cheese Head Screw size for the Speakers.
I still have the old style I bought from England years ago, but want some for stock.
It's those tiny nuts, and the name of the metal washers that mount with them on the circuit board.
The UK nuts are wider or thicker in height compared to the USA made nuts.
Oh, and Jim Marshall told me he used red metallic enamel paint for the inspections on the terminals, not red dye.
I told him I used all the red colored metallic Testors brand enamel paints to match what was on the amp. There is like 3 or 4 shades of the red metallic. And on the Filter Cap replacements I use a red & yellow Testors paint to mark the tops of the filter cap terminals using a Q-Tip, so no need to clean a brush., like the originals. It just looks clean and tidy when you paint the cap terminal circles on the F&T caps. When you look at all the Testors red/maroon metallic colors you will see how close they are. Seems the 1971-73 amps used a darker color than pre-1970, it was less metallic. Q-Tips work well to mark the terminals for inspection.
Would be mighty kind to know what's in your mind,
Oatie
