JAN Philips 7581a for Two Rock

[klatuu]

My early Topaz was equipped with JAN Philips 7581a's and I'm looking for replacements and not having much luck. Hoping someone can point me in the right direction for a set of these tubes or a suitable replacement!

TIA

I used them in my super reveb, pro reverb, and prosonic head.

For my style, which was more of a harder rock, I did not find the SED 6L6 tubes to be a drastic step down. However, the 7581As are great tubes.

I would think if you put some want to buy ads up on the forums, you'll find a set eventually.

7581a is a military/industrial version of a 6L6GC with a little more output. They can be replaced with a regular 6L6GC with a slight loss of power and headroom. 7581a's are getting scarce and expensive , but being NOS will last a very long time. Check with Mike K. (Bluestrat on this forum) he's showing one pair of GE's on his site .

Mine are still running fine, but due to the increasing scarcity of the 7581a's I thought it might be wise to get some spares. Supposedly the Topaz (what limited number were produced) was developed due to the lack of NOS tubes K&M had on hand; mine being serial#3 evidently got the NOS tubes while they were still available. They are outstanding tubes! :AOK

How many do you need (pair, quad)? I have some.
