GR-1361A
This is a variant on the unit oscillators. The attenuator is here at the front and it has a closed cabinet. It uses the same PSU. That is connected through two plates and a bold to the oscillor. In the pictures they are separated. I added 4 busses to the back of the psu to feed the unit oscillators too.
