Vintage 2 x BROOK TRIODE Tube Mono Pre-amps with powersuply
Tuesday, October 20th, 2020
Extremely rare, extremely good. In triode circuit with 4 x steel tubes 6SJ7. Normally the pre-stages are supplied with power from the output stages. My technician master built a separate power supply so that the preamplifier can be operated with any other power amplifier. Both preliminary stages were completely overhauled. There is a lot of information on the net, just google Brook 12a3 pre-amp. Extrem selten , extrem gut. In trioden schaltung mit 4 x Stahlröhren 6SJ7. Normal werden die vorstufen mit strom von den endstufen versorgt. Mein techniker meister hat ein separates netzteil gebaut damit können die vorverstärker mit jeder anderen endstufe betrieben werden. Beide vorstufen wurden perfekt general überholt. Es gibt viele infos im netz , einfach mal Brook 12a3 pre-amp googeln.
