Supro Blues King 12 OEM Exact Replacement Tubes - years of replacements

Description

I am an owner and big fan of the Supro Blues King 12 amp - I have several of them.
The amp only uses the 1 - 12AX7 preamp and 1 - 6L6 power tube.
I have an arsenal of guitar amp tubes. Every time I buy a tube amp, I remove the chassis and experiment with changing out the tubes, and seeing the differences that different tubes make.
With the Blues King 12, I tried out 8 different preamp tubes, and 7 different power tubes.
The great and original tone of this amp only works with the original stock OEM tubes.
The exact preamp tubes are nearly impossible to find, and the power tubes are out of production, and actually impossible to find, at least with my efforts.
These tubes are exactly what you will find in your Blues King 12 and can preserve that tone for years to come since there are 6 changes of preamp tube, and 4 changes of power tube.
It is possible that these are also in your Delta King 12, but I really don't know for sure.
You are getting 6- Ruby 12AX7 WBC HG preamp tubes, and 4 - Ruby 6L6 GCMSTR power tubes.
