Hello Richard, 

I’m trying to repair my Eventide 1745M. I have a problem on the input board. Schematics can probably be found on page 51-52 of the manual, which is unfortunately missing in the PDF file. I could kindly ask you for a copy of these two pages. It would help me a lot.

Howdy, Roman,

I’m WFH and don’t have access to a physical copy of the manual here.  Sorry.

Richard

Hi Roman, Here is the schematic. Thanks to Richard’s previous kindness I’ve now fixed 3 of these wonderful units though I have to say they really know how to die. If I did any more I would start by changing all the tantalum caps and the volt regs as they blow up while you’re fixing something else and take more chips with them when they do so you’re fighting fire a lot. Good luck.

Hi Lincoln, 

 

Thanks so much for copying page 51 of the Eventide 1745M service manual. Now the input board and generators are OK, it behaves normally, you can set the delay, etc. 

Unfortunately, only one board works on the output. Other boards are broken. I would like to ask you for a copy of page 52 (probably the output diagram). Without it, it is difficult to find a problem. It would help me a lot. Thank you!

PS: I sent you an email, but I don’t know if you received it.
