It seems everything in the 1A4 is in a
hard-to-get-to place! I'm having to do some work on the channel 2
attenuator module. It was easiest, by far, to actually swap the
channels 1 and 2 modules just to work on the bad one... Anyone who
has seen the 1A4 knows how tricky even that is...
But all that is a price I'm very willing to pay for the superb
capabilities of it. :) :)
@ Albert: Thanks for the source. - I may look into them.
- What I failed to make clear is that I'm in the UK, so
would find it easier and more convenient to deal with
people over here. But, if I can't find a more local
supplier, Qservice may be the place.
@ snapdiode: Yes, I'll certainly give that eBay etc a try.
- I've already doused the switches with Servisol and
there's definite improvement in three of them, but the
behaviour isn't back to normal yet.
You're right, they are not in the most accessible of
places. If I've got to do any major dismantling, I hope I
don't damage anything else in the process...
Thanks for your response.
@ All: If anyone else knows somewhere in the UK who may
carry these switches, please feel free to tell me
