SOLD- Mesa Boogie KT-88 power tubes for sale. The box on far left is new and unopened along with some fuses. The other 2 boxes are tubes pulled from a Mesa Prodigy. One of those 4 tubes is bad- I do not know which one and have no tube tester to find out. The price on the these 3 packages from Mesa was over $400, so I have here 5 good power tubes for a lot less. $50 shipped-48 CONUS ONLY- Paypal ok.
