Re: 2720 VCO tuning

Re: 4700 front panels

the labels come in 4x2" 10 per sheet
also smaller and 8 1/2 x 11 - one label.

I decided on the 4x2 size as I expected the full sheet would be hard to manage. although I guess I could have just cut it down after printing.

Re: 4700 front panels

I managed to put together my bal mod and mixer.
I used transparent mailing lables cause my waterslide paper is pooched.

the panels are far from great but they look way better than my beat up Paia originals.

Re: 4700 front panels

I tried waterslide paper - the results were horrible. I'm guessing the paper was 10 years old or more, and is seriously expired. I've ordered more on ebay and plan to pick up transparent labels from Staples.

I have howerver determined that my mixer and balanced mod are functioning.

Re: 4700 front panels

I found 6" x 18" aluminum at Canadian Tire. should be available at home depot in the US. look for threaded rod (3' and 4' lengths) that's where the sheet and strip aluminum is. they also have nice 1.5" and 2" by 3 feet strips that are thicker. the sheet aluminum cuts easily with tin snips but may cu...

4700 front panels

I need a panel for my mixer and balanced modulator, also an ADSR.

I can get the material but would love to have correct artwork for silk screening them.

anyone?
