Listing is for a N.O.S. LOWER CHASSIS PANEL for a SUMO "MODEL NINE/MODEL NINE +" AMPLIFIER. This item is a NEW UN-USED OLD STOCK vintage amplifier part in excellent condition. Item may show minor signs of being stored for 30+ years but only upon close inspection. This aluminum panel has BLACK ANODIZED FINISH (silkscreen lettering on rear and/or SUMO logo on front may be included while supplies last, Please message me for specific availability). The Model Nine Amplifiers were available both with or without front panel/faceplate so the gold silkscreened "SUMO" logo is not included on all panels so please specify which model you have and we will do our best to provide correct panel for you. We also have blank panels no silkscreen added on either side. We have several other NOS and pre-owned parts for the SUMO Model Nine (transformers, heat sinks, switches, fuse holders, hex head screws, most all  internal electronic parts) and several other makes & models available, please ask for more info./pics. Thanks.
