Warranty issues on pre-owned equipment and dealer demos

Pre-owned Lamm equipment:
We provide a 5-year warranty to the original purchaser of Lamm products obtained through an authorized Lamm dealer.  Pre-owned equipment does not carry the warranty; however, in certain circumstances we might be willing to sell the remaining balance of the 5-year warranty term (counting from the original purchase date) to interested individuals.  There are a number of conditions involved; therefore, each such case will be reconciled individually.

1 Screwdriver type for hex screws used to unscrew the top and bottom covers of Lamm equipment is an Allen 7/64" hex (available from Lamm)

What substitution tube types are  recommended for the L2?
1 Instructions for replacing the tubes in the L2 Ref.

1 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.

1 We don't offer remotes in a conventional sense of the word.  However, we have a  "remote turn on/off" feature available when the L2 Ref. 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 L2'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 L2'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.

1  You don't need to use shorting plugs unless there is a strong RF in your area.   In this case, you should just put the shorting plugs in the unused inputs of the phono preamp

1 What's special about the load selector switch on LAMM power amplifiers  M1.2 Ref./M2.2/M1.1/M2.1?

1 If one RCA input is used, the other must always be shorted with a shorting plug (supplied with the amp) -- otherwise, hum will be present.

IMPORTANT -- as a first-time user of the amps, you should pay particular attention to operating the "load" and "power" switches located on the rear panel of the amp.  These are so-called locking switches, which means that they don't operate by a simple flick.  You have to first pull the switch toward yourself and then move it up or down.  This type of switch is used to prevent accident flicking.  There is a Warning insert right between the plastic cover of the manual and its title paper.
