[DSP-10] Front panel LEDs & jack grounding

[Liljeqvist W7SZ]

Hi Michael..I use the +10R and +10T points as much closer to the "front 
panel". Did not use adhesive as my grounding arrangement keeps the LED's 
firmly in place..Also drilled for a snug fit between LED and box. Be sure 
to use
1K resistors between LED's and supply. Works great on both my DSP-10's. 
Have a picture of this arrangement and would be happy to send if you supply 
your E-mail address..For some reason, this reply goes to the reflector and 
not you? The pix isn't all that sharp but shows the area in question..73,
Larry  W7SZ
