Q. Is there a BS colour number to match the Ferrograph / Vortexion deck paint?

Q. The reels on my Ferrograph 2A seem too low, the tape scrapes bottom flange.

Q. I've been given 2 power amplifiers and 2 control amplifiers from early Ferrographs. 

They look very similar, but one uses EL84 output valves and the other EL41. 

Other valve types are different too but I can't recall what they are from memory. 

I thought all these machines used the EL84 circuit. Do you know what model the EL41 

variant is from?
Q. How do I deal with a noisy Volume control?

Q. Why after spraying the main control switch, my reel motors won't work?
