I bought a set as replacements for the stock Sovtek KT-88's in a Rogue 88 amp. Huuuge improvement in sound, not even close. They sounded fantastic. Made me wonder why Rogue didn't just offer them as stock in the amp. As the above post says, more transparent and better on both top and bottom.
Has anyone used the Electro Harmonix 6550 tubes ?
I currently have the Svetlana 6550 's in my VTL & think they are great . Someone suggested the EH 6550's and said they are the best 6550's . What do you guys think ? Thanks!
