For sale is a rare vintage RCA OP-7 portable mixer amplifier. This unit originally came from CBS. This one has been modded with direct outputs, with 4x UTC A-20 transformers (which adds approximately $600 value, plus the labor to install these mods) feeding 4 XLR output connectors as well as the main XLR output connector. This mod makes it very useful for a variety of setups compared to stock models. It's all original internally otherwise, tested and working. Due to the age of the original components, our techs recommended it could use a recap as preventative maintenance and for reliable long term use. We can perform servicing for additional cost if desired. Contact us if you want to add servicing to your order. The unit includes the front cover (not pictured, but it is included).
