Mikko	Re: Screen Grids Article Great articles, (feels like I) know a bit more about screen grids too haha. Now, what is cheap vs. more expensive ways to get that lower Vg2 voltage for a pair of kt88's. Let's say I'm aiming for this. Class: AB1 Va: 550V Vg2: 300V (..says application data) Ia: 2x60 Ig2: 2x1.7 Zout: 4500 Pout: 100W The PT I have now (or soon) is Hammond 378CX and the OT's for trying are Hammond 1650R and 1650N. Thanks! Mikko
