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, ..... 

Standard Matching within 3mA.

The gold standard in 5U4GBs. 1960's through 1970's. Some labeled  5AS4 which is an EXACT replacement.

$65

Great military grade 6V6GT for all 6V6 needs. Original boxes. Standard matching within 3mA. None of our 6V6s are for use in Jim Kelly Amps. The plate voltages are too high.

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,

One matched pair (within 4mA) in plain white boxes in stock (6/22/26)

These work great in old Fenders requiring 5881's or 6L6's. Good substitute in 6L6GC amps where less headroom (breakup at lower volumes) is desired. Also make great replacements in Fender Deluxe's where more clean headroom is desired. Just plug into your Deluxe and re-bias, no circuit changes required. Excellent choice for most 6L6GC amps if you'd like a little less clean headroom. These hold up well in amps with plate voltage up to 470 volts.
