Vintage H.H. Scott Type 335 Stereomaster Tube Wide Band Multiplex Adapter .The Type 335 was originally designed for a high end mono tube tuner with MPX output unit that converts mono into stereo.
This unit is highly regarded and has become a bit of a collector's item. The unit powers up fine, see picture of glowing tubes. Front panel power light does not light up, likely just a tiny light bulb that needs to be replaced inside the power light. Due to vintage nature and not having matching gear to test, sold AS IS... Lightweight, so shipping via standard (parcel) post will be reasonable, likely $30.00-$40.00.
