Warm sounding 6922 Type Tubes

For 15 years, I preferred the large D and/or the large O getter Amperex bugle boys or equivalent.  They tended to have a full bottom end, very sweet mids and slightly recessed highs.  Lovely, just lovely.  

I have avoided the search for Vintage Valves of this type for some time.

There are prices being seen almost appreciated 100% since I was last searching.

My purchasing method, where an agreement with the Vendor is in place that a Tube will be returned for a refund, If my friend with their Valve Tester proves the Tubes supplied measurements are not quite close, when measured on the friends calibrated tester. This method has assisted myself with getting top draw Valves.

With the present prices such a agreement will be even more important, if I have to enter back into being a buyer.

Caveat Emptor - Caveat Emptor, most valves supplied will produce a sound, but what type of Valve is being supplied.

As made known in a previous thread on the E88CC, a New Matched Pair of Gold Lions, had one Valve measuring quite unusual when tested and it was strongly advised not to use it as the Circuit could be detrimentally damaged.

Yes late vintage Siemens can be bright.  I bought some years ago for a preamp and almost immediately put them back in the box they came in.  I think I still have ‘em somewhere 🤔 

@fleschler I’m returning the Mullard to Brent in exchange for a Bugle Boy. He described the sound of the Bugle Boy just as you had stated. 

Here’s the latest update. On a whim I decided to swap fuses to see if there were any differences. I was using a recommended Hifi tuning copper supreme for its warmer presentation. I replaced it with the stock fuse and the upper glare was reduced further. I then installed a Synergistic SR20 fuse that I used in the past and with the same results. It seems to me the better fuse might have extended the frequency response to where it was affecting my tinnitus. So now I will be using the old SR20 fuse from now on.
