Hi,
I got a pair of CARY CAD-300B SE monos from my friend. I tried it out in my home. I noticed that the mid and high are pretty good. Unfortunately it does not have sufficient bass.
I checked the circuitry. It employs 6SL7 SRPP as driver. The B+ for 6SL7 is 450Vdc. The cathode resistors are 4.75K. The bottom cathode resistor is bypassed with a 500uF 25V electrolytic capacitor and a 2.2uF Solen film cap.
The coupling capacitor between the 6SL7 and 300B is a 0.22uF vitamin Q like capacitor. The 300B is with fixed biasing and the B+ is 440Vdc. It is set to 60mA bias current.
I am wondering if any one have worked on this Cary 300B and any experience in improving the Bass of it.
