Titel: internal view original DR103
Beitrag von: kentuckytukker am 11.04.2020 17:28
Hello,

With ref to the YAH100 kit from the TT-shop owners I herewith attach a few pictures of an original DR103 chassis. Note that the main turret board is having 2x31 turrets, while in the TT-kit this is just 2x30 way. Also the projection of the potmeters concerning the soldering lugs is upside down.

So ?
The YAH100 has also a Bias-Adjustment while the DR103 has none.

Regards, Dirk

The photographs are just to show how Dick Reeves has designed the amps in those days. For those owners who want to adapt an adjustable bias I refer to my other articles showing detail how to modify the original design
