These brought my Marshall Mk II 50 watt Lead back to life! I tried EL34 tubes for about 10 years but they always sounded congested. Not anymore! My tube spring retainers even fit again.I did modify the preamp to Atomic Soldano specs before the switch.  But now the tone controls are so responsive that I can go from clean to crunch with just the twist of my guitar volume. Not possible with EL34's. These are damn impressive sounding for the $.
