Brimar is making a comeback. The people doing it are getting the equipment and getting it working again. See, The Great British Valve Project.

Here is a link, no date except Copyright 2020.

And they have newly produced tubes for sale, buy now buttons.

Purchased some of the new production Brimar ECC83's and EL34's from them a few years ago.

Compared the matching data with original Brimar ECC83's I have with my simple Orange VT1000 tester.  The originals matched at much higher values than the new production at the time.  About the same as current 7025 version tubes. 

The new Brimar EL34's are harder to determine as the closest I have are original Mullard EL34 xf2 style.  The original Mullard's tested at higher levels.

Will be interesting to see if newer production are testing at higher levels like the originals.   I am still using the original Brimar ECC83's in some amps that originally came with them.

And they have tubes for sale, page with copyright 2020, and a buy now. So evidently they are in business.

An enjoyable article and how wonderful that the volunteers donated their time to restore those machines. I vaguely remember some record pressing machines being restored.

How do the new production tubes you have sound Hal? Are the 83s close?

They sound very good in my guitar amps.  Still have guitar amps with the original Brimar's running from the '70s.

New vs NOS, an apple to apple comparison. I have just found out that at least some tubes are out sourced. I take it
that money, or equipment refurbishing are limiting factors?
