DB54 - 2254 style compressor {update 22.10.19}

[MoJo]

Some pics from my units which I built in 2019. Everything works as it should except for the meter tracking (which was reported before from other users as well). I used BC184C, BC214C and BC441 for the transistors. It might help.

I used BC184C (with 2 perfectly matched ones where specified), BC214LC (could not find BC214KC anywhere), and I don't know where the BC441 went so I can't tell you what I used there. Thank you Undos, every perspective helps to rule out a potential variable.

Transistor orientation looks good now on your unit. also no other errors detected at first glance. as far as the bypass off/on position is concerned, according to the instructions under point 6, the up position (LED green) has the compression switched on. but on my device it is the other way round, the compression is switched on in the down position. i am pretty sure that the instructions are wrong. I would assume that compression is switched on when the toogle switch is pointing downwards.

I may have put the LED in backwards Undos; believe me when I say one of my nicknames is "Wrong Way Joe"! Hahaha!
