Audio Valve Challenger (Germany) 115/150/180 mono tube amplifier pair (2) including all tubes as shown. Output tubes are EL34 so are quoted as 115wpc in its present configuration. WPC changes with output tubes applied. Recently serviced and all tubes test well and have plenty of hours to go. Each mono amp is very heavy at about 40-45 pounds each due to massive transformers. I am Missing the factory packaging and top plates of each chassis but does not affect performance. Prefer pick up in Rockville MD but will consider driving to meet or working with your packing service to pack and ship. (Or send me the two factory boxes?) Sorry I will not personally box and ship these monsters but will work with your shipper. All tubes as shown are included and originally retailed for $10,000. Dont settle for cheap Chinese amplifiers and do consider these German Quality amplifiers.
