Description
The original level meter of the Telefunken RC300 cassette deck had bonding issues and was not repairable. Therefor a replacement was needed.
There's a LM3915 audio level meter solder kit or already soldered module which can be used as a replacement. I went with this one:
Bausatz LM3915 Audio Level Indicator Lautstärkeanzeige DIY-Elektronik zum Löten | eBay
To meet the level characteristics of Telefunken, the LM3915 needs to be replaced by the LM3916. I ordered this one:
IC, 1 Stück LM3916, LIN; Display driver, 10 LED, level meter, DIL-18, '03 | eBay
So in order to fit the total different level meter PCB into the right place of the original recess of the housing, I created this new holder.
You have to use at least PLA+, PETG or ABS (the clips will easily break during snapping the holder into the recess).
Unfortunately I didn't take any real pictures after putting everything back together.
