Increasingly rare, these ex BBC racks are made to very high standards.

Fully modular rack system with EDAC  I/O on the back and multi pin power connector.

Industry professionals will surely recognise the quality of these units.

Condition is very good, bit dusty but can't sell as working as don't have means to test, so 'as is' the condition is very good and I have no reason to believe there is anything wrong with these modules.

4x AM7/13 High Gain Line AMPS

2x EQ3/34, O.B. Line Equaliser, 

1x EQ IN / Line module with connector.

Details on the EQ3 are;

"O.B. Lie Equaliser for local lines not exceeding 16 Km in length. Simple resonant type with a choice of two inductance-capacitance ratios and a fixed frequency of 10 KHz. Loss and damping are adjustable by potentiometers on the front panel. CH1/65A. DD 1976. DDHB 6.180(80). DDMI 6.309 (77)"

Thanks for looking.
