Recommended Solder 
The kit must be assembled with 63/37 Rosin Core solder. The recommended diameter is 
0.031 inches. I use Kester 24-6337-8800 50 Activated Rosin Cored Wire Solder Roll, 245 
No-Clean, 63/37 Alloy, 0.031" Diameter. That is 1 pound of solder, which is much more 
than you’ll need to assemble the PR-102 kit. 
Warranty 
With the exception of fuses, Akitika will replace for free any parts of a correctly 
assembled PR-102 that fail within one year of the date of purchase when the amplifier 
has been used in home stereo applications. It is the responsibility of the kit builder to 
install the replacement part(s). This warranty applies to the original purchaser only. It 
does not apply to units that have been physically or electrically abused, modified without 
prior factory authorization, or assembled with other than 63/37 Rosin Core solder. 
Akitika LLC’s liability shall in no event exceed the cost paid to Akitika LLC for the kit.
