Vacuum Tube Testing

Joseph Solomon · Post by **Joseph Solomon** » 9 Mar 2007 10:21 am

Here's one for you electronics buffs. Is there a substitute for these tubes----6CS7,7199,7027. Any help would be appreciated.

Thanks, Joe

Do you actually meas a 6CS7...or a 6SC7 (common in old Fenders)?

The 7199 and 7027 are currently made by Sovtek - The Tube Store online has them, and any other Sovtek dealer can get them. There is no substitute for the 6CS7, so you have to hunt for NOS tubes. If it's actually a 6SC7, you can use a "Substi-tube" adapter and plug in a 12AX7.

Hope that helps.

Jim
