Default Re: The "Sussex" Homebrew Valve Tester.

Latest on my front panel.
The printing was on A3 thin card and glued to the aluminium panel and then covered in clear sticky backed plastic sheet. (meant for covering book covers)
The parts are fitted, but no wiring as yet. The back has a mains inlet, 2 fuses and a computer fan.
I've decided to add some small 10 amp relays (cost about 75p each) for the heater voltage selection to avoid the possibility of damage to the rotary switch passing a higher current than specified and also for the switch to link direct/indirect heater cathode wiring.
