zZounds Gear Experts Say...
Pick up a modern replacement for 7591 power tubes to make your amp sound like new again. A factory 24-hour burn-in period ensures great tone out of the box.
Overview

Our platinum matching process consists of a 24 hour tube burn-in period followed by a bias (plate) current measurement in milliamps. Please specify matched tube grouping (ie. pair, quad, sextet, etc.) when ordering (no odd-quantity groups, please).

"Electro-Harmonix 7591A output tubes"
Verified Purchaser
zZounds has verified that this reviewer purchased this specific product from us.
Tubes are beautiful. However, the tubes are taller than all 7591A tubes I have used in the past. Thus, if one sufficient clearance above his existing 7591A tubes, the Electro-Harmonix tubes are fine.
Musical Background:
In 1966 I sang in a group with my future fiancee. The group liquidated, but I am engaged presently.
Musical Style:
Progressive Jazz
