INTRODUCTION 

 

 

 

Thank you for choosing a MATCHLESS brand instrument amplifier. Your amplifier has 
been carefully hand-crafted using only quality materials. The chassis of your amplifier is 
completely hand wired employing construction techniques of military electronics 
manufacturers. We utilize point to point wiring instead of a printed circuit board. The 
wire used is silver coated stranded copper in a Teflon jacket for extra resistance to heat 
and decay. We use porcelain and mica filled phenolic tube sockets that are shock 
mounted to a rugged welded steel chassis. Our hand wound transformers are designed for 
100% duty cycle. Vacuum tubes are selected for tone, low noise, and performance. Output 
tubes are carefully matched for power, balance and long life. This kind of craftsmanship 
and attention to detail enables us to offer to the  original purchaser our unconditional 
no-time-limit guarantee. 

 

If a defect occurs in any MATCHLESS amplifier chassis, the repairs will be 

made at no cost to the original purchaser, indefinitely. 

 

MATCHLESS amplifiers are ruggedly built, and aside from periodic tube or 

indicator lamp replacement, should require very little maintenance. We have designed 
every MATCHLESS product to be a trouble-free workhorse and hope you enjoy yours for 
many years to come!
