Hi all, I have been reading around recently (Reeves, LondonAmps, MavenPeal etc..) with respect to power scaling. I have visited the relevant sites (londonpower and MP) read all the material etc. Since i am not insanely proficient with circuitry yet (but i do understand some fundamentals), i wonder the following. Using a power scaling method, you can overdrive the power-tubes by using less voltage to them. Thus you get the familiar/desireable tone at lower volumes. The tubes last longer, the amp runs cooler. This can be achieved with either a extra variable transformer or valve or something. My questions. 1.How do you overdrive the powersection using less voltage? 2.Is it in general reliable? Does it mess up the signal path? (i have the option to be bypassable). 3.Is it as effective (or more effective) than a Hotplate, valve switching, triode/pentode solutions? I know that the RG88 that i heard online (thanks dbx) was AWESOME at talking levels. Thank you for your replies.
