Product Reviews
Great tube and these guys are just the absolute best to deal with, the shipping was fast and they have an awesome supply of tubes, if you need amp tubes ordered through the mail use these Amplified Parts!!!
absolutely awesome buisness to deal with, helpful, informant and good shipping, I have recommended Amplified Parts to some friends, great dealing with you guys, will continue to by my tubes with you
It's a fine tube, made my Marshall DSl 15 C red channel usable and the green channel still has the gain factor it was designed to have. I recommend this tube.
Try My Current DSL40C Tube Load-Out. All Tubes Purchased Here:
V1 - JJ-ECC823
V2 - JJ-5751
V3 - JJ-ECC83-MG
V4 - TAD 7025-WA
Bought this tube on a recommendation from a colleague. It drastically dropped the gain factor on my Marshall DSL40C without reducing gain on the 'green' channel. It dramatically smoothed out the 'red' channel and allowed more saturation without getting muddy. Best ever DSL40C upgrade...
