Up for sale / trade is my Reiner Preamp which is a real gem. Massive gain, pure tube, and so cool. It does not disappoint! Look up JGR on this website and you’ll view his amazing creations. Highly revered! JGR will more than likely extend the warranty to the new owner provided that you contact him. How cool is that? Selling price on the Reiner is $900 USD shipped to the USA or within Canada.
