[cwg2018]

How do I contact Peter Diezel to purchase Ruby 12AX7AC5 HG+ 678 tubes for my VH4?

Doug has some.

Those from Doug's are different than the 678. The 678 has one triode that's got super extra low microphonics. Should say 678 on the label. I have some somewhere.

Jens Kruse may have them in stock. He used to.

Ok... my bad I didn't know. Thanks for the correction.

No worries, they're not a commonly used tube really. Unless you've retubed a Diezel you've likely never had the need for them.

Does the vh4 need these? Regular 12AX7 won’t work? Asking because I have a vh4 coming this weekend.

V1 of VH4 takes them. Or is it V2? I forget but I thought it was V1.

Its not "Needed"...but Recommended. You'll be fine without the 678's. They are just great for the needs with regard to microphonics and noise. There are a ton of guys who probably dont even know about these tubes who use Diezels. Dont sweat it.
