How about M-125 from tubes4hifi.com ? 125w monoblocks using 4 6550guys just wondering if there are any designs out there for more power.
goal is to build mono blocks somewhere in the 80 watts each range.
i have had many other amps in the 40 watt range and sold them all over the years.
Speaking off a quality PSU ... one that starts with a voltage doubler ??
And all the heater on one winding ? I prefere separate for the finals.
i should have mentioned this in my first post
idea for tube amp is first for a visual knock your socks off view when they are first seen.
push pull design
and 4 or more tubes per chassis.
guys i have been looking all weekend at designs.
came along into this at some post link
Schematic - Genelex 100W Tube Amplifier @ AmpsLab.com
what i don't understand is this claims 100 watt from 2 kt88 when most others claim 35 or 40 watts from only 2.
can more kt88 tubes be added to this amp and will adding more mean more power?
thanksOh it will do it, but the tubes will wear out very quickly. There is no escaping the reality of TANSTAAFL.
PPP can be "a can of worms". Getting quads of tubes closely matched for gm runs costs up. Reliable vendors work hard to get well matched quads that can be sold and they charge accordingly.
JMO, tweak the Heath W6M design and you'll be highly satisfied.
100W from a pair of GU-50 is easy, and they last long. However, they require 800+ Volt B+ and 8-10K power transformer.
Heath claimed a conservative 70 W. from the W6M. Build with a better B+ PSU whose impedance is low and whose current reserves are high and you rate to get pulses at 2X+ the continuous O/P power.
thanks guys for all your ideas
i have looked at so much over the last few days .
eli i got the heath circuit from a post you did on another site in 2013
how do find the needed output and power irons for the w-6m?
i'm such a novice that the ru-50 amps with 800v b+ has me scared.
i think the heath will be more friendly for a first build.
if any of you were to set out to build a w-6m what would you use for the best kt88?
