Verified PurchaseWanted to try an EL34 valve in an amp I've just bought to replace a 6L6. Thought the hotter E34L would suit my style. I can get fantastic Marshall style crunch and plenty of added gain over the 6L6, exactly what I wanted!
Fast delivery and well packaged. Proper customer service from Stewart. My first purchase but will definitely use again.
Your nice feedback is greatly appreciated 🙂
Verified PurchaseNeeded a replacement EL84 valve in an amp I've just bought as I didn't know how many hours were on the old PM valve. The new JJ sounds a little louder and the balance is very good.
Fast delivery and well packaged. Proper customer service from Stewart. My first purchase but will definitely use again.
Official dealer. Valves tested in-house. 180 day warranty.
