Vintage Masco MA-25 amplifier tube head harp guitar amp etc PROJECT! This is an old Masco MA-25 MA-25 all-tube amplifier. Originally a PA head, but in recent times many have been converted for guitar or harmonica use. This one has never been converted. UNTESTED and can be presumed to be currently not working properly. I don’t see any obvious replaced parts (I think those Sprague orange drops could be original but that is a guess) so I didn’t plug it in; I’m sure the capacitors will need either replacement or possible reforming and I have not attempted that. Also, it still has the original multi-pin speaker jacks and I don’t have anything to use with those. Also, the inputs are screw-on style except for one RCA input which is for a mono phonograph. I hate to put things IN CAPS but I’m really trying to avoid someone getting this, deciding it’s too much work and then returning it. You can see cosmetically it looks pretty good. Missing two of the six screws that hold the bottom on but the four present do the job. I did test the tubes and all the small tubes (the 7 series preamps) test at 100% or better on my B&K 707 tester (which doesn’t mean that if you use your tester you might not get the same results as testers vary); the 5U4 rectifier also tests strong. One of the 6L6 tubes tests in the questionable range (around 60%) , other a bit better so you should plan on new power tubes anyway. Power cord possibly replaced as it looks newer. There is some finish damage and wear to the chassis and cover but overall it looks pretty good cosmetically and the Masco logo is intact. The maroon knobs are original. Could be a good project for someone with the skills and time but if not you should find someone with experience (Skip Simmons is maybe the top guy in the country for Masco restorations). _gsrx_vers_1233 GS 8.1.1 (1233).
