Hello
I just opened up my Model D to re-solder a wire that had come loose from the third oscillator.
When I put the circuit boards back on and closed it up I’ve found that there are now some issues with tuning.
The first thing is that the intonation of the keyboard is now off on every oscillator. eg. If I tune the first G on the keyboard to a perfect G, the high G on the keyboard will be closer to F#.
The second thing is that when I switch the oscillator range switches, a note on a high range is a lot higher than the same note on a lower range. Sort of the opposite of the first problem.
Has anyone experienced anything like this?
Could I have knocked something on a circuit board or broken a connection somewhere?
Any help would be greatly appreciated.
Thank you very much
You probably won’t like my answer, but it’s the most honest and effectual help I can provide:
Please refer service to qualified personnel only.
There are some things that cannot be resolved over the internet and this is one of them.
You need to take it to a qualified tech.
I probably will go to a tech but I just wanted to make sure it wasn’t something simple before i shelled out £500.
