Verified PurchaseAnother perfectly balanced tube for phase splitting duties in a modified Custom Vibrolux Reverb - every time I come here I am reminded of the superior customer support I receive compared with larger concerns. I remain a very loyal customer.
Verified PurchaseThe standout feature of these valves is the detailed testing of each valve. A full summary of the testing parameters was provided along with tips to bias your valve set correctly. Many outlets supply JJ valves but not all test and grade them. I look forward to playing the Marshall JMP 2203 with a new set of valves. The old Mullards finally gave up after 47 years !
Nice to see you appreciate our efforts
Verified PurchaseGreat value sockets. I particularly like the 'wrap round' pin receptors. They were easy to fit to a Marshall JMP2203.
Official dealer. Valves tested in-house. 180 day warranty.
