Purchased some of the new production Brimar ECC83's and EL34's from them a few years ago.
Compared the matching data with original Brimar ECC83's I have with my simple Orange VT1000 tester. The originals matched at much higher values than the new production at the time. About the same as current 7025 version tubes.
The new Brimar EL34's are harder to determine as the closest I have are original Mullard EL34 xf2 style. The original Mullard's tested at higher levels.
Will be interesting to see if newer production are testing at higher levels like the originals. I am still using the original Brimar ECC83's in some amps that originally came with them.
