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,
Got the Jan Phillips tubes. Thank you for the great advice, these sound great in my Tone King. I could not believe the difference, especially on the Lead/Tweed channel. Very articulate and clear and very nice break up. I have been buying tubes from you for over 15 years and have always had great service and products from you.
Thank you,
Tim
Hi Mike,
NOS in original boxes.
When these are gone try these!
East German EL34s (manufactured by RFT) with great tone. Last of the reasonably priced NOS EL34s. Not recommended in amps with plate voltage over 450 volts though many cases of success at up to 500 volts have been reported. Bottle has dimple in the glass on top. 4 staples in the plates.
