I don't have any spare tubes for 6SN7; I only have a pair of 300B. But all the tubes are light up. When I turn it off, the "light" are normally fade off. Everything looks normal; but no sound comes out from the AMP.

Hello, is there Cary 300 SEI user or tube AMP users experience bias adjust. About a week ago, I turned on the 300 SEI; the tubes light up and LED is on; but when I tried to play music. There is no sound. I used my the other amp to doble check other components that work fine. What do you think...

I just use tube AMP about half yr. Could you tell me how I figure out which tube is going belly-up? I put the vol. between 10 to 11 o'clock. So I dont think I exceed the 15 watt per channel; plus, I use it to drive my K1000 only. There is a switch for high/low gain. Do you think that would...

Do you know how much electrician usually charge for grounded wiring for one gang box (a set outlet with two sockets). Do you have any suggestions of good surge protectors. What's difference between regular socket (two slots) and grounded socket? Is there any sound quality difference between...

I realize there are no grounded wire outlets place in my living room. I haven't schedule an electrician to check if there is one in my living room. I wonder whether it's harmful if I plug my power cable into regular socket (w/o grounded wire person) with an converter. Since I have no clue with...

I just move into my new apartment. I found there is none of socket is grounded in my living room. I am going to have an electrician to intall a new set of socket with grounded plug. Since I have to change the receptacle, I wonder if it's worth to buy upgraded receptacle for my system. I am...

According CaryAudio website, Cary 300SEI just need 3 mins to warm up. I wonder if any Cary 300SEI owner can share their experiences and suggestions. thank you!!
