I ordered a pair of Tung-Sol 6SN7GT valves and plugged them in. After the amp warmed up I noticed they seemed to be glowing brighter than the pair for the other channel.
I switchedf the amp off and then noticed that I had been supplied with 6SL7GT.
Are these a viable substitute?
Should I ask the retailer to provide the ones I ordered?
I complained and they sent me a pair of Electro Harmonix 6SN7EH not the Tung-Sol 6SN7GT ordered.
So I will have Tung-sol GT’s on the left channel and Electro Harmonix EH on the right channel.
