We recommend replacing 6C19P and both 12AX3 tubes about once a year to maintain the best performance of the preamplifier.
Instructions for replacing the tubes in the L2 Ref.
Ventilation slots located on the top cover of the preamplifier and its power supply must not be blocked and the distance between the top cover of the power supply and any horizontal surface located above the top cover should be at least 4 inches.
We don’t offer remotes in a conventional sense of the word. However, we have a “remote turn on/off” feature available when the preamp and the following LAMM amplifiers are used in the same system: M1.1/M2.1/M1.2 Ref./M2.2/ML3 Signature. This feature is activated by using remote control cables that are ordered from us (one set — 2 pcs. — of remote link cables is $49.90).
If you wish to order these cables, there are two options available regarding their lengths:
(1) one cable of the actual length between the preamp’s power supply and the amp, and another a short link between the amps OR
(2) both cables of actual length, each running from the preamp’s power supply to its respective amp
This feature is activated by “remote” switch(es) located on the front panel of the preamp’s power supply.
