Title: Kay model 710 reverberation : Help
Post by: Rick R on July 03, 2025, 06:40:35 pm

I’m hoping that someone may be able to help me with power transformer information on a Kay model 710 reverberation.
Someone had removed the original power transformer and wired in a 9V battery connector.
Everything else is there with the exception of a 500uf cap.
I’ve replaced that as well as all of the electrolytics.
Someone else has posted a diagram showing a 16V transformer, but I’d like to get the transformer codes if there are any as well as a definite output voltage.
Any help would be greatly appreciated.

Thank you!
It’s weird, because I saw the thread, but somehow missed the post where he gave the voltage as 15.9V.
