The Amp Garage

Maybe I could reverse bend the chassis (inside out)? Then rebuild into a head version of the Tweedle Dee

Going to strip it for spares. Output is 2x 6v6 and 5Y3 recto. I think it is some sort of attempt at a 5E3 type circuit

BC AUDIO has nothing on this builder 😂. Took a chance and purchased from a deceased estate. Figured it is worth it for the tubes and PT + OT.

Yip us ex Hi-End Audio guys need counseling . Just for kicks, I recently built a Tweedle Dee with KIMBER KCAG (99.9999% pure silver). I need help . Nice build man .

Beautiful work

Thanks for your post.
That's wonderful. That idea sounds like its right up my alley.

Put the GZ34 back in and prefer the sound of the amp “hot”. I am not getting any red plating. I don't mind replacing tubes 😎. I’m not a professional player, so the tubes should last a while. I know you guys don't like the bias calculator, but anyway.. this is what I got. My only problem is the heate...

Looking good! Let us know how it does with the band. Did you add any mods to the standard Tweedle Dee circuit? The beer is just for a size reference, I guess ;^) Martin, no mods yet. Guitarist used the amp last night and loved it. I briefly played it and thought it needed a bit more headroom. We do...

Thanks Martin. Will let you know, and thanks for the help. Most appreciated . Yes the beer was for size reference

Calling her done. Thanks for all the help on the forum. Time to try her in a band situation. Fine tuning and tube rolling to come.

Cabinet Tolexing. My pet hate. But I am improving. Will load everything today, just waiting for a face plate

Anyone done anything with the AO-71 stereo amp?
