History - The Oneida LS-206A/U Loudspeaker Assembly was the original the matching military set for the Collins R-390A receiver. This dual speaker was a component part of the AN/GRC-26 Mobile RTTY Communications Hut. The receiving portion of the GRC-26 had two R-390 receivers that were rack mounted with a CV-116 Diversity RTTY Converter and the LS-206. The dual speakers allowed the operator to monitor the signal while tuning in each receiver. Once the RTTY signal was tuned in on each receiver the speakers could be turned off. Inputs are 600 ohm.
Restoration - I stripped and repainted the faceplate with the original Battleship Gray color. I rewired it and made a new gasket. replaced the two speakers with modern day Jensen PM Alnico equivalents but kept the original transformers and grill cloth. I also replaced the old terminals in the back with exact replacements. It is mounted in a Hammond Manufacturing rack mount cabinet.
Dimensions: H 18" x W 21" x D 13"
