Here is one (1) used TMC (Technical Materiel Corp.) Model SLM-1 (serial no. 305) Sideband Audio Level VU Meter Monitor Unit.

This unit is designed to monitor the operating level of two separate line-level unbalanced audio circuits. As you can see in the photos, the beautiful engraved and filled front panel is in pristine condition, and the rest of the unit is in good cosmetic and physical condition as well.

Please note that the power transformer has failed, and as such, this unit is sold for parts or repair purposes only, with no possibility of return, so please be guided accordingly.

The power transformer may be replaced with any unit that provides 500 VCT at 35 Ma, and 6.3 VCT at 3 A. Such transformers are commonly available. My guess is that Hammond offers a similar transformer, but I'll leave that up to you.

I acquired this SLM-1 many years ago, with the intent of replacing the power transformer and making good use of it, but I never did anything with it. It has been stored in a dry, clean, conditioned environment since then

I am also including in this sale the correct Hubbell Twist-Lock AC input power connector, which can be seen installed in the rear of the unit.

As with all electronic equipment of this vintage, this item is sold in as-is condition, for parts or repair purposes only, and with no warranty or possibility of return.

Please look at the accompanying photos carefully; what you see is what you will get, and feel free to e-mail me with any questions you may have!

Please be sure to see the many buyer positive feedback comments I have received as a seller here on e-Bay. Bid with complete confidence, as I have 100% perfect positive feedback, and I have been a member of e-Bay since 1999!
