6922 Replacements for BAT VK-300x

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.

the best replacement is any make of ECC85 i have replaced my ecc88/6922 in my audio note equipment and mf x10d with dramatic results.

Thank you, so much, to all the respondents. I did check out the Brent Jesse site, and I may place an order soon.

I've been in touch with a couple of vendors, and it looks like a good short-term replacement is going to be the 6N23...Mang53's suggestion was repeated by Jim McShane.

I also picked up a pair of Mullard 6922's from a fellow member. I'll be leaving the cover off of the BAT for a while during my experimentation.

Chris I am confident that an ECC85 of the cheapest make will always beat a Mullard 6922, you will get that natural tonality much more with the ECC85.
