Wrong valve supplied


#1

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?


#2

No. The 6SL7 is more like an octal ECC83 compared to the 6SN7 which is more like an ECC82

Yes. ask for the correct valves to be sent.


#3

Not even close. As Guy says, they’re very different and could cause damage to amp or tubes. Get a replacement.


#4

Thank you I’ll speak to hotrox tomorrow.


#5

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.

Do I keep them or send them back?


#6

They are the gold pin Electro Harmonix 6SN7EH version if that helps.


#7

Your call. Have they stiffed you on cost?


#8

No, a straight swap. I know the Electro Harmonix are significantly dearer.

I just don’t want a different sound on each channel.

Mix em up ?


#9

Yes, assuming the amp uses two per side, just use different types so that each side is the same.


#10

The standard EH ones are not great in comparison to others I have tried. I’ve not tried the gold pin ones though.


#11

Sounding great
