4 x JLM BA (Single) in 1U case

[chris p]

I'm in the process of building a 2U rack containing 8 x BA Dual pres with metering, so the question is whether I cannibalise my current BA's for the tranny and 99V, or sell the unit as a going concern. So there's four of these pres in a 1U case

* Input transformer JLM 1:4
* Switched variable impedance (150, 300, 600, 1K2 and 2K4 off the top of my head)
* 99V opamp
* 48V pad and phase switches

Comes with JLM 48V supply.

Photo up soon (unless sold before hand).

Offers or swaps in the $1K2 ballpark - its about $800 worth of kit, plus the case and power supply adds another $100 or so, the rest is wires, sockets and assembly.

Any pics of the front and back of the unit would be greatly appreciated.

NOTE: The variable impedance has 4 positions, not 5 - no 150R, just 300, 600, 1K2 and 2K4

Hi Chris,

This uses the 99v and no output transformer so its unbalanced out correct?

Er, no. The output is balanced electrically. Refer to the schematic one the JLM site, and the strap across the IC pins technique for using a 99V with no transformer.

Oh, and the unit is SOLD. Sorry, should have posted that earlier.
