Taking Sonavors advice Justin (Bulldog) asked if I would take a look at this.......I cant resist a challenge and I'm not doing much just now so have agreed to take it on..... when I say "me" I mean the forum of course ;¬)

Installed the replacement into Justins machine, set up the switches and gave it a go.....works perfectly now, arm lowers in a controlled manner.....its still falling short on a 45rpm disk however, so that will be addressed at the same time I clean the slider switch contacts.

Time to unravel this lot and replace them with Rudi custom made mounting assembly.

Rudi's brackets are a very good solution and a good fit.......

I like to run a test after each of these steps, it makes it easier to go back and identify any blunders if you know the points at which everything worked fine following surgery......so far all is well

Next up Rudi's LED conversions for the control panel.....straight forward enough, chose to use the wire connectors as opposed to the pins as I thought the pins would be more fiddly

Control panel switches followed......for most of these I left the leaf in place and just un soldered the saddle, I decided to try out a glass fibre pen to do the cleaning after seeing a video by Rudi.....nice and gentle and very effective.

However three of the leaf's had to be removed due to the contact side being underneath or in the case of two of them double throw....

i noticed these switches where quite sticky, not as free as they should be....this has caused me problems in the past when i used silicone grease on the buttons thinking it would lubricate them and make for better operation, it actually made them stick....so I have given these a clean with alcohol and will leave it at that.
