2235B Rebuild

[Rockyhill]

Starting a thread for my rebuild effort. I bought this ~10 years ago but rarely use it. Has some hum and pop issues when shutting down. This will be my winter project - expect some questions from me!
Here’s the first. Is this date code October 25, 1978? Or 1976?

Probably 1976. Some of the sages here may know better.

1976 falls within the date range according to this site:

Are you going to do a full restoration? I have a 2235B also, I've been "saving" it; I'd like to follow along. I hope you will post parts lists as you go through it
