1U-13 - Single Rack Space Chassis 13" deep


In Stock
Product Code:


Aluminum rack-mount chassis 1U tall (1.75", 44mm) and 13" deep (330mm). Textured black paint, except on the interchangeable front and rear panels which are smooth white and smooth black.

This chassis is ideal for a single or multiple preamp kit(s) plus power supply. For instance, our PSU-PRE preamp power supply mounts horizontally, with the PRE board(s) mounted vertically using right-angle brackets. Tubes are necessarily horizontal. Ventilation is good. Use with any of these London Power kits: F-PRE, D-PRE, LP-PRE, M-PRE, S-PRE or Z-PRE, and/or with BFX and LINE.

Ideal for fully featured stand-alone effects loops using our BFX kit or multiple BFXs powered by PSU-PRE.

Our 20W power amp kit (PA84) and matching supply (PSU-20L) will fit in this chassis as a stand-alone single channel power amp. There is room to add any one of the London Power preamp kits, noting that the PSU-20L can support eight 12A_7 tubes in addition to the PA84 tube complement. There is room to add Power Scaling (SV1 or SV2) and the Single Ended Mod (SEM).

If you wish to use octal-based preamp or power tubes, please see the 2U or taller chassis.

See our Rack-Mount Chassis page for more information.
