NOS NEW 4CW25000A-R 25kw TUBE $1350: Purchased Electronic Enterprises 4CW25000A-R (25KW) in original box years ago and was told was NOS Never Used. I cannot verify or test but sure looks never installed. I can ship tube in original box UPS Insured but will be pricey for box is quite large. Box has bottom foam but top foam missing. No problem as I have plenty of bubble-wrap to protect during transport. These 25KW tubes are insane pricing even if pulls so NOS has real value. I am selling as-is untested just the way I purchased with statement is NOS by previous owner. Only Method of payment is Zelle. Any questions please ask. Many pictures available upon request. Price $1250 plus shipping.
