“Bass less floppy, and midrange has more detail and clarity than the previous Sovtek 6550’s in AR amp.”

“It is working good. It needs more break in time. This power supply tube is better than the previous, Tung-Sol from the Tube Store. The previous owner,bought for the ARC Ref.5 se preamp.”

“For what it is, very good ! My amp can run either 6550 or EL34. This tube has very smooth highs, and powerful bass. The midrange became more recessed than running EL34. Especially when I switched to a tube preamplifier rather than running direct from DAC. Every piece of equipment including cables and power cords make a difference. Your mileage may vary, but this is a VERY SOLID tube with a dynamic sound and iron fisted bass.”

“Great output tubes, they were easy to bis w/o fear of them overbiasing them in my amps. My amps are hard on tubes but these last longer than any others I have tried except NOS GE6550As - at $125-200 per tube.”

“Easily biased all eight tubes with one adjustment on three tubes after one hour. After that, they hold perfect bias. Huge sound improvement over my old 6550’s. I waited way too long to replace. So these tubes restored the ear pleasing sounds emanating out of the mono blocks. I was so pleased with the cost. Saved about 350.00 USD over what CJ quoted me. I am ordering another 12 tubes but they do not discount their tubes. With great prices on most tubes, I am fine with that. Shipped quickly and safely. Very smooth on line experience. Only exception is you have to look around the site to find what you are looking for. But overall, great products with reviews and a quick ship. All good here.”
