HD 212 130W ID detection...?

waltergrund

Hi,

I tried to date my amp and for now I found out, it must have been built between 77-79.
Here's some infos:

It has only 4 tubes, the standby-switch at the back and the ultra-heavy original speakers.
Inside is a hand-written number on the cassis that I read as 137. The last digit could also be a sloppy "2" which would result in "132"

Serial# C006336
Transformer# EIA-606-718
Transformer# EIA-606-823
small Transformer# EIA606-740
Cassis NO 2475-130
Speaker ID is 67.7906

It's a lot of fun finding out/searching that stuff...!

I'd appreciate any help!

The number may simply be a way to note which baffle in a production run goes with which box. Other parts of the same box can have numbers that are now hidden by tolex covering.
