Remote driver stage for Be Bamp in a tea box
|
To increase the volume level of the Bread Board amp (Be Bamp) a driver stage was built. This is the original cct. used in the Merlot amps with some components upgraded. The is no volume control or input cap and pure silver wire used in the signal path. Russian Military caps (paper and foil) were used for the inter-stage caps. Low ESR caps used where possible. The timber box is bitumanized Al foil lined. Tube is a Russian 6N1P.
The Be Bamp can now deliver full volume to the point of clipping. Well short of clipping a high volume level can be obtained with large 91db sensitive 3-way tower speakers. With the driver stage being remote other driver stages can be matched to the power stage and share the power supply. This provides another level of experimentation and flexibility with the over-all system.
