(3) 274B Rectifier Pairs - Sophia Aqua Blue, TJ Full Music and Valve Art each..Sophia Aqua Blue - just bought these new June 8th 2022 from Sophia... about 100hrs of use
TJ Full Music - hours unknown, came with the amp
Valve Art - hours unknown, came with the amp My amp is a Art Audio PX25 which can use a 274B or CV378 rectifier... I had been using the TJ 274B and decided to try a new pair of the Sophia Aqua Blue 274B as my PX25 tubes are Sophia Mesh... however after trying the CV378 again, I prefer it so I am selling all my 274B tubes... Lower price...and free shipping...Will be packed well...
