Collins 30l-1 for sale: Hello everyone.
This one is a Collins lineal amp. It is unmolested(no mods) although the 811 tubes had been replaced with Svetlana tubes 572B(no more than 5hrs) making it easy in the P/S and they are more forgiving). Power supply still factory original. It loads 700+ watts of power with 80wtts drive. Cosmetically is about 80 percent. I have owned this amplifier for 25+years. Packaging and shipping is doable but it will cost probably a good 100+dollars, or you are welcome to pick up at my Qth in Brandon FL( willing to drive 100 miles from Tampa to meet,.) I will include a copy of the manual. The price of the unit is $650,00 plus shipping and packing. More photos available upon request. payment payPal friends& family usps M/O for check untill it clear. No warranty or returns(you know why!!) You are welcome to call me at my phone### is in the listing, but sent a test message first..
