    Home built. I have somewhat of a electronic background. Starts in the middle of the page with the schematic, second one is the final. Ignore the other stuff. Just shows I have a scatterbrain mind.

    Thanks man. I will look it up but I don't think I will understand it as I'm tech challenged. I played a tone king gremlin the other day and liked the blackface side but the tweed side didn't have much clean headroom and I like tweed cleans. It was also bigger than i need. We live in a small house and I want a champ sized amp so I can leave it out all the time.

    Well, I've had both over the the years.

    Hands-down winner was my SFVC that I installed a push-pull volume pot and some minor circuit mods to bypass the tone stack but still retain the trem circuit. Given the two are similar in basic circuitry beyond the tone stack and tremolo, I had the best of two worlds in one amp! You wouldn't believe how alive it got with the tone stack bypassed, and a tweed Champ with bias vary trem was heavenly!!

    Now I 'm getting nostalgic and remorseful about selling it...

    For me, Princeton, not Champ of any ilk. The 8" is just not happening for me. (I have one, love to diddle on it, but don't really want to play seriously on it.) All those great records with Champs are not being played or heard through a Champ -- they're recorded and mixed and played back via some other device.If we're talking live amp tones only, I'll take the Princeton.

    As said the two circuits are pretty much the same but the tone control was taken out and the Blackface tonestack was dropped in front of the volume control. To make up for some of the loss of the tonestack the second stage cathode resistor was bypassed with a capacitor. I met the tone control components half way and rather than the tone control being 1M and the treble control being 250k I use a 500k pot. Then it was just adjusting the two capacitor values to get back to the BF curve. I tried to get down to two switch pairs but needed three because if you had the bass control down you could mess up the response of the Tweed side.

    Would have been nice if you could use a push-pull switch on the bass control to change from one to the other.

    Double yep.
    There's stuff you can do with those tiny amps if you mic them...mics love little speakers, it seems...but, otherwise, they always sound dinky to me.
    I love tweeds and have several, but I wouldn't bother with a Champ unless a real good deal fell on my...even a Princeton 5F2A runs the risk of sounding dinky.

    I have a silverface Vibro Champ that's a snarling little beast with the tone stack bypassed. And I love the tremolo. It's a great little amp. I also put an extension speaker jack on it so I can run it through a 2x12 or my '67 Bassman's 2x15.

    That's part of the appeal of the Goodsell to me. It's got a ten inch speaker but a Champ sized cab.

    I play my '64 Vibro Champ at home more than my tweed Deluxe clone. Something about the tone, best sounding amp I've ever owned. Add the Flint reverb, and I'm in heaven. Great practice amp.

    Well I have a mystery on my hands so I'm not sure. I have a Blackface Champ with an output transformer dated '66, a power transformer date of '67 on a '68 Silverface chassis (according to its stamp). I guess I like them both!

    I used to have a 59 tweed champ about 25 years ago. I traded that for a set of Ping irons. Currently I own a 69 Champ and very happy with it. :D

    It's a tough call. I can say that my 2 favorite amps - that is, two that I own - are an EC Vibro Champ and a Princeton Reverb RI. I play those most of the time. The Vibro Champ was the real surprise. I thought it would be a one-trick pony, and I suppose it is in some ways, but it has surprised me again and again. The hotter the tubes get, the better it sounds, and it has nuances that I hadn't suspected were there.

    For use with pedals, black or silverface all day.
