Description
In our opinion the M8137 Mullard CV4004 remains one of the very best sounding valve.
Boxed plate with round getter! Heavy soldering on base.
Large U-shaped posts rods with Single bar supporting the getter (please check pictures)
Few of these left around! Both triodes are well balanced to produce (like all ECC83 Mullard) a stunning sound
Price for Mullard M8137 boxed plate ECC83 £ 75 each.
We also have the Mullard CV4004 KB/AD 12AX7 ECC83 a special version with 17mm plate and ‘asymmetrical’ plate £ 100 each
Matched pair; matched quartet or more available; please contact us for quantity etc.
