It was suggested that I also post this here in the Amp Room sub-forum. I recently built a Hiwatt DR504 clone from a Ceriatone "Hey What 504" kit. I used Mojotone transformers and put it in a custom 1x12 cabinet made for me by Sour Mash Guitar Cabs using brown "country western" tolex. Full build report with pics here: Ceriatone Hey What 504 (DIY Hiwatt DR504 clone).
