Hi Steve,

these tubes are not the same. The 5694 cannot be regarded as general alternative to the 6SN7! It can degrade the performance if the circuit around if that cannot work well with the much higher plate resistance. The higher mu can be a benefit in some circuits but also a disadvantage in others.

Also important to note that they have a different pinout. Otherweise unexperienced readers might just try to plug these into their 6SN7 sockets.

Best regards

Thomas

What is the slightly used New-Old-Stock market?

No, really?

When did ''NEW'' stop meaning not used?

Thank you Thomas. Understood and point taken. Yes, just like the 6F8G an adaptor must be used. The difference of course is the specs are virtually the same as a 6SN7.

That is OK because I know that for me, in my Oppo BDP-95 w/Modwright mod, I have run these tubes for hundreds of hours and they are the cream of the crop in my set-up.

Look up top where it says "Thread Tools" and click "Subscribe". You should then get email notifications.

Also consider the 7N7 tube. A loctal version of the 6SN7 that sounds quite good.

On the recommendation for the 7N7, it is the loktal equivalent of early 6SN7GT and because of the loktal base it is still far cheaper than comparable vintage 6SN7.. Don't get fooled by the "7" it is in fact a standard 6.3V filament type. IMVLE there are no bad 7N7..

Hi!

+1 on the 7N7 recommendation! Contrary to the tube mentioned above the 7N7 is electrically equivalent and only needs the socket change or adaptor

Best regards
