i like the Master Volume model 2204. 50 watts more than enough to blow out your ear drums, particularly with modern "high sensitivity" speakers. I just refurbished one for my wife's uncle. 1978 mfg date. Just re-capped the electrolytics, replaced a pot, cleaned, re-bias. The thing was mint! I instantly nicknamed it "Slash", for good reasons. Classic heavy hard rock sound. I really was impressed with the build quality and design for manufacturing. As opposed to the CBS fender years, Marshall did a real good job with keeping quality but also getting cost reduction. All passives on circuit card, rest is point to point wired. At same time I was refurbishing his Fender 1973 silverface deluxe reverb. What a quality disaster. I found 5 production screw-ups, including some missing components, a filament wire not soldered at all, etc. Amp never ran right and would only stay alive a week. its a wonder he kept it. I now brought it back to originality with high quality parts and it sounds amazing. I should create a post for this refurb.
