Går vel under vintage dette også ?
Fikk dette i dag,låter bra med litt during i effektforsterker. Men det kan nok fixes
The RHB-10 is an enormous dual-mono powerhouse with two 1000W low-leakage toroidal power transformers (yes : 2x 1kW !) working with dual rails : low power is output in Class A, while higher needs switch the circuit to Class B.
Total power output amounts to 2x 200W (8 Ohm, 20Hz...20Khz) with little distortion.
The four big caps you can see below amount to 88,000µF and the rest of the componentry is top of the red pops : 0,01% and 0,1% tolerance Vishay resistors, 6N pure stress-free copper wiring between output stages and WBT speaker terminals, glassfiber PCBs with doubled-up copper tracks and solid copper bus bars.
Also dual-mono regulations all over separately feeding power-supply, output stages, pre-driver stages, protection relays and indicators separately through filter caps and rectifiers.
The first stage of the pre-driver stages is a fully complementary push-pull differential amplifier, followed by two emitter-follower stages.
Thermal and DC drift are dealt with through referenced center-point voltage.
The output stages make music with Darlington quadruple parallel fully complementary push-pull - symmetrical and mirrored "top, bottom, left and right" ; Sanken power devices.
