Hello CPFers .I have the following question for you:
What is the visual difference between TLE-300M-EX and TLE-300M drop-in?
As far as i know the TLE-300M is printed on the board

but i am not sure if this can be read without disassembling the unit..:candle:
Thank you.

p.s. what emitters are used?
