Adding a Herron VTSP 3A/360 Preamplifier to the system.

You're welcome.

Gentlemen, suddenly both channels have become noisy on the Herron Line Stage. I  I had one tube that became noisy, so I bought a new set, and it sounded just great for a few days.

Now, both channels are making a kind of scratchy sound (it can be heard if soft music is playing).

I have contacted Keith, hopefully I'll hear back from him soon. Nothing else in my system is having any issues.

Thanks and regards,

Dan

I have owned & enjoyed successive generation Herron Preamps - I started with the VTSP 3a Ro1, then the Ro3, and now the 360/ESP ......I have actually been lucky enough to have the Ro1 & Ro3 simultaneously and was able to do an AB comparison, and later an Ro3 & 360-ESP as well...cant say enough nice things about them. I saw a bigger difference between the Ro3 and ESP than the Ro1 vs Ro3.

I can’t wait to get the REF upgrade.

BTW I enjoyed the youtube interview a lot! He is able to bridge the science and art of electrical engineering and a pair of good ears for the enjoyment of music.

I wonder if Herron will be represented at Axpona this year...looking forward to it.

@islandmandan Surprised you got no reply to your noise issue. It does sound like a noisy tube. Did you get it sorted?

I think part of my problem is I had my head where the sun doesn't shine (at least not much anymore). It turns out the issue was a 3C24 tube in my amplifier. I have no idea why I was so convinced I thought it was the preamplifier, but that's what it turned out to be. 

So, things are going swimmingly at the moment, which is how I like it. In my current condition, just keeping things dusted and adjusted is about all I'm able to for the most part.

I saved the best for last, though, the music has never sounded better.

Best regards,

Dan
