A while ago I bought three lovely 5M4's from Trade Me - all restored quite easily apart from the volume. They turn down fine but move the volume control clockwise just a little bit & the sound is very loud. All three radios work like this - I wish I had paid more attention to this before I broke out the soldering iron...
On two of the radios I replaced the volume controls - they were intermittent & a squirt of contact cleaner didn't fix it. (Yes I used log pots)
They all have the resistor network across the speaker & connected to the cold end of the volume control too. I replaced them just to be on the safe side - I used the existing values 'cos this modification isn't on the circuit diagram.
Any ideas on taming these beasties ,please?
Also may I take this time to thank Mr. Dunford for his website. This an excellent resource:)
