While waiting for valves, etc. I had a look at the speaker. It checked out fine but looked horrible so I gave the cage a coat of paint and put on a new front seal so it now looks a bit better. The speaker mounting board is a cheap piece of chipboard so I may replace that later once I get the set working. The wood is very soft and when the speaker was originally mounted it pulled the mounting bolts half way through so it might be a source of vibration, etc.
There are two tweeters fitted - I assume electrostatic - and this is the first set I've worked on that features these. They measure well over 120meg resistance - I was wondering if that's OK?
The speaker cloth is two-tone in colour. To me it looks terrible but the brown stripe along the centre is intentional. I'll replace this with something nicer if I go ahead and make a new mounting board.
In general the cab build quality is somewhat inferior to the Grundig 3028 that I did but I'll reserve judgement until I hear the sound. If it sounds good then I'll put up with the poor cab quality.
Next I'll get started on the power supply......
Cheers, John
