2U-8 - Two Rack Space Chassis 8" deep


In Stock
Product Code:


Aluminum rack-mount chassis 2U tall (3.5", 88mm) and 8" deep (203mm). 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 typically horizontal, but can be vertical if an insulating board is sandwiched between the chassis bottom and the audio PCB. This applies to preamp tubes only - EL-84s are too tall for a vertical orientation and must be horizontal in this chassis. 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-PA84) 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-PA84 can support three 12A_7 tubes in addition to the PA84 tube complement. There is room to add Power Scaling (SB-2) and the Single Ended Mod (SEM).

If you intend to add a preamp, please use the 2U-13.
