Title: Reverse voltage hurt a Belton brick reverb?
Post by: tone seeker on February 08, 2021, 10:35:28 PM
 Well it was bound to happen, at some point. I was building a Rubidium reverb ( DBA
Reverberation Machine), and I wired the 9 volts to the board backwards.
I already replaced the 78l05, and the TL074 IC incase it fried them.
Will reverse voltage take out the Belton BTDR-3H.
  I'm not getting any effect, so I was curious if it could be fried?

Those Belton Bricks are really voltage sensitive with an operating range of 4.5 to 5.5 volts. 
If your 5 volt regulator broke down, I'm guessing you had -9v directly to pin 1 on the BTDR-3H.
I think this would cause the Belton Brick to fail. 
Maybe others who have experience with this brick could chime in.

Sounds very plausible!
