This is a 7 volt version of the super-expensive, impossible to find 6DJ8. Smooth highs that maintain extension without being bright, with great detail and texture in the mids.
7DJ8/PCC88 are a great choice. They are absolutely compatible with virtually any product that uses 6922 and 6DJ8 Whether it's an amp, preamp, CD player, whatever. You still need to pick a good one of course. And one that meets your sonic requiremements. And Upscale Audio doesn't sell any sucky ones. But understand this: You are in essence getting tasty stuff for half what you would pay if they were labeled 6DJ8 instead of 7DJ8. They will operate the same. Trust Uncle Kevvy on this one.
Made in West Germany for Telefunken by Siemens. These come in original boxes, and test beautifully. Most all of them have tested low in microphony, so we do not have any Driver grade at the moment.
Platinum grade - The best of the best. Lowest noise and microphony with the tightest triode balance we have available. This is typically 10% or tighter, but may be higher depending on available stock.
Gold grade - Low noise and microphonics with a triode balance typically between 15% and 20%, but may be higher depending on available stock.
Logo and box may vary from picture above. Price includes matching in any quantity you need at no extra charge.
