For Sale:The highly reviewed and rated SR 71A portable headphone amp by Ray Samuels.
This is the 'newest' edition as per details given on Ray Samuels website. Purchased 12 months ago, the amp has been used for about 30 hours in total. It runs on 2x9v batteries. It is extremely compact (1 pound coin kept in picture for comparison), is in excellent condition (barring couple of minor scuffs). I will throw in couple of bands to tie this with an Ipod perhaps?
