Will last another 53+ years and be worth more after all the modern chinese made junk with their microscopic, flammable, surface mount components, noisy, toneless circuit designs & irreparable flimsy printed circuit boards have burned up, been discarded &/or traded to Guitar Center for MORE modern chinese junk.. !! Why do the manufacturers continue to sell chinese junk? 50% of my repair business involves vintage & modern chinese offerings that burn up, are unreliable, problematic, costly to repair and DECLINE in value.. ! EXPERIENCE TRUE VINTAGE TONE, RELIABILITY & INCREASING VALUE. Original hand wired circuit board. Installed are my high quality, road ready, Ampmedic power supply/filter capacitors. Installed are 4-Russian EL34′s closely matched within 4mA, plate/watt dissipation (bias) set to the industry standard of approx. High quality and reliable Sprague Atom caps have replaced the old board electrolytics. All 4-power tube sockets have been replaced for secure tube mounting. Installed is a 3-prong power cable with earth grounding, so the not needed Polarity switch has been disconnected. Carry strap and hardware are almost new. The case is in remarkably good condition for it’s age, with minor Tolex damage to the corners which have been touched up and almost unnoticeable.

Contact cleaner is designed for momentary contacts and NOT CONTROL POTS. !! I replaced all the polystyrene mustard caps, which, over time, become stressed at the wire connection points to the cap body and separate. Especially prevalent in early HIWATT amps with their especially short leads. Installed now are reliable, high quality and open sounding Sprague Orange Drop Polypropylene caps. Because this early Marshall has the high B+, 490vdc mains trafo, this amp is loud and clean like all early S/L’s should be with air between the notes and more frequencies being revealed with a black background and extremely low noise floor even when increasing the volume. Truly world class tone and reliability you’ll enjoy. You will be as proud to own this vintage investment as I have.. Stay tuned for more vintage electronics from my collection priced to sell. !
