Product Reviews
When one vintage Mullard started to die on my Dynakit St 70 I started looking for backups. NOS seemed overpriced so I got these. Theyre much better than expected. Bass are more open than the Mullards while the mids and highs are breaking in nicely, comparing favorably to the Mullards. I have the vta 70 driver upgrade on my dynakit with triode switches and they seem to break in better in tetrode mode.
Great quality replacement.
I bought a matched-quad set of these tubes to replace the output tubes on my Van Alstine modded Dyna ST-70. With the original output tubes I was unable to adjust the bias, in either channel, to the correct 1.56V. This is usually systematic of aging output tubes. The new tubes biased correctly with no problem, and sound great. Highly recommended. Also shipping was very fast.
