1960's TOPAZ Treble Booster / Tremolo [DATA DUMP]

Post by rafmax »

Hi,

It's been awhile since I last posted material... Here is a Topaz treble booster / Tremolo. Probably mid 60's.
Featuring 3 Mullard OC71 transistors stamped "T3PP". Maybe date code reader wizards could narrow an approx manufacturing date using these or some caps stamps.
I haven't fired it yet because I need to make special Jack/TV antenna connectors cables :badteeth:

Here are the first pics avaialable :chillin:

No Idea, all I can tell is that it stands by the "boost" control... :chillin:
