Just got these antique tube recievers from junk, the rca-victor is a SE with 6AR5 output and 12AV6 driver, 100VAC, double A.M tuner. when i test it Umusok
despite the fact that I have 100V xformer(find out later it was caused by leaky PSU filter caps,) it fried the 6CA4 rectifier tube :'( so I temporarily replaced it with SS diodes, the filter caps originaly is 20mfd, replaced it w/ 150mfd., further test showed that all capacitors(electrolytic specially), were way out of tolerance, i fired it up once again anyway, I was surprised as it was dead silent while idling, tested some Stan getz/Joao Gilberto cd's, if the JLH class A gave me goose bumps, these piece of junk raised all the hairs in my bodies
,its been 25 years since i last heard a tube amp sing; despite the fact it is only 5W/ch, very transparent from mid to high driving my Altech Lansing sattelites, its more than enough in a 20X20m room.another thing, I tapped the output from 12AV6 driver via 270k resistor to isolate the high impedance of the tube amp and feed it to the low Z of JLH amp, wow even the SS amp sounded like tube amp! the only diffrence is the SS amp has got the punch,(JLH is 12W/Ch). Right now i stripped the whole RCA-Victor down to the last wire and tube socket, rebuild it as amp only minus the bulky AM double tuner. how about the GE reciever? Have to set it aside for a while,..so it is posible for SS amp to sound "tubey" by feeding it with a signal from a tube driver. Sir JOJO D. might have a more detailed explanation.
