6922 Replacements for BAT VK-300x


I purchased a pre-owned VK-300x integrated, and one of the 6922's is microphonic. I replaced both tubes with a spare set of Sovtek's that I had laying around. I'd like to put something a bit more refined in their place. Has any BAT integrated and/or preamp owner here experimented with anything else that they would recommend? My preference is to lean towards warmth over an analytical sound.

I've tried to call Andy at VTS, but I'm not sure he's still selling tubes based on a couple threads I've seen here. I've purchased from Kevin at Upscale, but his "didn't buy gear here" prices are quite high. Anyone here purchased from Tube Depot with success?

Thanks,
Chris

I checked out the site, thanks. It's a very informative website. I'll have to get in touch with him after the Holidays!
I agree with trying Brent Jesse Recording. I have bought tubes from Brent on numerous occasions. He is a top notch tube seller. He has several varieties on hand, and is quite knowledgeable. If you are not happy with your selection, he will allow you to return them and try something else. You can't beat that.
Hi Chris, I'm using a pair of early 70's Amperex made in Holland 7308's from Tubemonger. These sounded better than the early 60's US Amperex that I tried with my 300x. Refined yet detailed. I've been using them for almost a year with no problems whatsoever. Good luck with your search and Happy Holidays, Gary
really got the tube of choice dialed right in for the Bat. Siemen tubes are sonically the clear winner in every way. They better any of the other nos amperex's[bulgle boy's included here],mullards and the telies. Another decent sounding tube for the Bat is the russian military nos 6n23ev's. These are "not" the same tube as the current sovtek 6dj8's or 6922's. They are smooth, have great bass weight, and are dead quiet,The best is they will last forever in the hard running Bat . The Bat's have always had a penchant for shortening the tube life of the 6dj8. As a matter of fact,the siemen e188cc was my tube of choice as it will handle a higher bias voltage than the gold pin e88cc and typically give one close to 5000 hours of tube life.One should only expect about 1/2 that life from the typical nos ecc88's. Hope this helps? at least it's a different view of the question...As for the vendor of these, I'm sure Kevin, and Andy are good to work with. However, make sure you place the Kat's up at the TubeMonger on your radar. Great service, inventory, no hidden agenda, and very knowledgeable.
cheers

You will be amazed by using ECC85 in place of the ECC88/6922. I have done this in every piece of equipment I have ever had with these awful 6922 tubes that always sound tonally lean. The ECC85 brings life colour and presence to the music. I have so far dumped the internal ecc88/6922 tubes in the following amps and used ECC85's Audionote DAc 2.1 balanced, Audionote M5, Musical fidelity X10D,etc etc. An expensive mullard ECC88 will be easily improved upon by the cheapest ECC85 everytime. So you can imagine that the Mullard ECC85 is the ultimate.
