Sony TA-1130 - Very early serial ?

[david winter]

Hi,
Out of curiosity, I'm about to service a Sony TA-1130 which seems to have a rather early serial: 550008.
The chassis also shows a sticker with 00374 stamped on it.
Is this one of the very first units to roll off the production line, or are there lower serial numbers for this model ?

Probably a 1971 early model. The original Sony TA-1130. That is the earliest catalog it was seen in.
