    Well I had posted before that I'd like to see some Flexi Innard Pics but no one ever posted any so I thought I'd crack it open.

    Having been a PTP snob for many years and fealing OK with Flying Leads the Flexi is quite impressive to gander at.

    All components are chasis mounted with Flying Leads except the Bias Circuit Pots which are mounted to a PCB but have very heavy Solid wires going from the pot connectors to the PCB.

    The Tube Sockets are very impressive looking with the Preamp Sockets having the Solid Wire again from the Sockets to the PCB. The Power Tube Sockets having Flying Leads.

    The PCB itself is very beefy looking. I dont think I've ever seen a thicker PCB in my life. The Traces look heavy duty and are heavy coated. The Board that holds the filter caps is mounted to the chasis very well as are the rest.

    Over all the build is very well made. It appears they went to great lengths to do this right. So far as I said before I'm liking this amp very much and hadnt even planned on getting one. The Construction of this thing from the Trannys to the Chasis to the Circuit is built like a Sherman Tank.

    My hat is off to to Ed and the guys at THD for a very interesting, different amp, that is well made and quite Flexible. :AOK

    My picture taking sux.

    From my untrained eye, it looks very nicely done.

    Wait, that's the plexi clone, right?
    :crazyguy



    sorry, had to.

    I heard Ed wail on one of these at NAMM, it sounded incredible.

    I've been a top PCB designer for 21 years, in January I quit my PCB design engineer at Cisco Systems to follow my dreams and go to GIT. I've always wanted to build a good PCB tube amp done right as I've hand built many of my own tube amps. I just couldn't justify the cost of a top fabrication house unless I was going into business. The reason PCB amps have such a bad name is that they are designed to cut every corner to save cost as possible.

    I must say this is the first PCB amp I've seen the innards of where the PCB was done right. Bravo THD! I give this design an A+! If more amps were designed like this, the stigma of PCB would be removed.

    No suprise really. THD build quality is always impressive. My old Univalve was solid.

    I wouldnt be worried at all with the Flexi on a gig. I wouldnt bother with a back up amp. The Trannys must be very robust being able to run most any Power Tube.

    I wonder if people post pictures of TV and Stereo PCB's on TV and Stereo forums, and discuss how they look?

    I've read that article before. He is right. The thing is though there are so many cheaply built PCB Amps out there it aint funny. Its like anything in life you can take your time and do it right or cut corners and not.

    As far as the comments about taking innard pics, I enjoy looking at the construction of Tube Amps. To me how an Amplifier I own is constructed is important. To others it may not be. To each his own. :)

    Dude, Cisco, huh? Very cool. Man, I wish you the best of luck! Please keep us updated with your progress as you go and follow your dream, as I'd LOVE to have a nice PCB option in guitarampworld. :)
