Manufactured in Mullard's Mitchum factory in the early 1980's. Nice military stock. Original white military boxes. Try one of these in your phase inverter or reverb driver socket (only if your amp calls for 12AT7s in these positions) in your Fender amp for a real upgrade in tone! Also superb in audiophile equipment (Macintosh), tube mics, mic preamps and studio equipment.
Hi Mike, .....
Number one choice for guitar amps where lower gain and smoother tone is required. These remove harshness in some guitar amps.ﾠﾠ
Standard Matching within 3mA.
The gold standard in 5U4GBs. 1960's through 1970's. Some labeled 5AS4 which is an EXACT replacement.
Mike: These are a BIG step up in tone from the stock tubes in my Dr Z Z28. Thanks! John Hey Mike, Got my tubes in last week and put them in my '59 Tweed Deluxe. Great sounding amp now. All original....nails the Neil Young sound now!! Thanks for the help!! Michael
NOS in original boxes. Only a few pairs left.
When these are gone try these!
Very low in noise and microphonics. Sweet top end.
"Mike, I just wanted to say that all the tubes sound GREAT. The GE 12AX7WAs are gorgeous, full and bring out the best in my guitar...I can't even put it into words. Thanks" Matt
I liked the first set of tubes so much I have to order another one to complete this amp. Thanks again Mike!
They are amazing tubes in my ENGL Savage. Beat out Mullards and Tesla e83ccs. Mike B
