EXPIRED: Fs. Pair of 300b JJ tubes

[Gremrock]

Item: 300b JJ Tubes New 
Location: Kingaroy
Price: $390 posted 
Item Condition: new/unused 
Reason for selling: too many 
Payment Method: Pickup - Cash, Paypal, COD Only
Extra Info:

I got a pair of amps with a bunch of spare tubes, I'll keep a couple as spares for if 1 goes, but ultimately when its time to replace them all, id rather try something else (for better or worse as they say) 

 

would also be open to trading for quality 6sn7s with cash either way, curious to try something special in the driver tubes for the Supratek.

Or a decent low output MC cartridge.

 

Won't be heartbroken if they don't sell, they seem to sell around $550/pair locally so I think I'm pricing fairly

 

I will put them in the amps seen In the picture and test they work before posting so they will have let's say 1 hours use for good measure.
