A picture of both the pre-amplifier and the phono-amplifier which it is powering. The preamplifier is a transformer coupled Telefunken AD101, as well on the input as the output, capable in receiving low-impedan

Solved the heat excess under the hood..
This was done by replacing the bridge rectifier for the AD101 to an aluminum heat sink on top of the transformers. Temperature within the chassis has dropped considerabl

A nice comparison between mesh- and solidplate, directly- and indirectly heated rectifiers.
From left to right: RGN4004, UU5, unknown (British?) and 2B-400.
So, the unknown (probably British made) is th Read more...
