From our review: "Bass response is firm and the sound remains detailed. I put some of these in my 59 Harmon Kardon and they were very pleasant to listen to. No ear fatigue and plenty of detail. They also performed well in my 53 Bandmaster. Lots of punch and some really nice bluesy sound when wound up."
From the manufacturer: "This valve is a rugged reliable replacement for any 6L6 or 5881 type. Perfect replacement for the output valves used in the reissue Marshall JTM-45 head and Bluesbreaker Combo amplifiers."

2002 HOT ROD DELUXE - new caps, filters, 330 switching resistors (Jensen C-12N, Bias 68 Mv)

Tried these new Mullards, because 3-YO Winged "C"s began rattling, and replacements are much too pricey!#1 BEST TONE; Tight, w/Smooth Bass, Fat Distortion: Bright Switch Activated & DeactivatedV1: Preferred Series 7025,V2: Preferred Series 7025V3: Mullard 12AT7WA / CV4024MUFFLED BASS & 'TINNY' on 'any' EQ config:-Bright Switch Activated & DeactivatedV1:Genelex Gold Lion ECC83/B759V2:Preferred Series 7025V3: Mullard 12AT7 ReissueTOO BRIGHT/WEAK BASS on 'any' EQ config:-Bright Switch DeactivatedV1:Genalex - Gold Lion ECC83 (Standard)V2: Mullard 12AX7 / ECC83V3: Mullard 12AT7 ReissueThe tone reminds me of TAD 6L6WGC-STRs. They're definitely not as sweet as Winged "C"s, but with the right EQ, you'll enjoy them. The Mullards took approx 2 weeks to break-in and show their stuff.I am happy...Hope these last a good duration!

UPDATE: These tubes pair best with JJ ECC83MG (Mid Gain) in V1&V2 with Mullard 12AT7 Reissue in V3:* 7 months going & bias still rock-solid @68* EQs can be moved just about anywhere with favorable results* Gold Lion ECC83 (Premium) and/or Tungsol 12AX7 tubes produce flabby/muddy bass and mids-highs are tinny* Tried these since Winged "C" tubes price too rich for my blood* New pine cabinet replaced OEM heavy, sound-muffling/smothering tolex cab - ooh-la-la tone!
