This is part of a silent key sale 

it is a mains  powered linear coveting 20 to 30MHz

so only suitable for 21/24/28 MHZ  

Tested briefly into dummy load with 1kw  output 

Given its age it  would benefit from cap changes and checking  

Mains powered and heavy. So collection only. 
600 pounds Ono
