Hello Mr Fixr55 ,
Here is the information off the Peko sight about the freq.
" The default frequencies for the RVB-2 are 115 Hz and 100 Hz, the latter frequency can be activated by
bridging a solder jumper: With JP3 open (not solder-bridged) the frequency is 115Hz. With JP3 closed (solder-bridged)
the frequency is 100Hz (see fig 5). The board is shipped with the jumper JP3 open (115Hz operation) unless specified
otherwise."

Here is the photo of the Vibrator  style I used and there is the metal spring clamp that is mounted to the socket that holds it and grounds the casing but one thing is I have not tried putting all the covers on yet .

this car radio has not been installed back into the car yet Also with the mechanical vibrator I don't know if it made that noise I can try it since I still have the almost new one that came with this radio it was bought on ebay !
Don't laugh but here is a photo of my powersupply

Sincerely Richard
