![]() ![]() I now suspect these either to be the originals, or early replacements. The stubby PM valves seem to show the dissipation, and the Phillips seem far more capable of tolerating the biasing. Im planning on replacing the electrolytics too due to the age of the amp.Īs for power, its a claimed 120watt, and from what ive read, or been told, it has quite a heavy bias. The auxiliary mains output has been disconnected, which is probably no bad thing since I wont use it. The pots are a little dodgy, it had some surgery to the internal wiring. using that advice, I'm hoping to renovate the amp a little. Yeah it works fine, probably due for new valve in the output side since the 2 pairs seem so very different considering they're both supposedly 6L6GC's.lolīasically, as I shouldve said in the beginning, this thread was the spawn of an earlier thread: I know little about valves but I look of them better. If you look closely they have radically different structures inside, and the Phillips ones look very interesting. The pre's are all " GE 'Electronic *something* " 12AX7, The left pair of output tubes are " PM '6L6GC' ", and the right hand side pair read something like " PhillipsECG '6L6GC' ", and also the letters " ha AGX " The writing on all the output valves, as well as the pre amp ones is very hard to read. All of the valves in general seem fairly old, though not really smokey. Here is some pic of my 120R, s/n t120r-047: If this interests people then its a bonus, but I think this restoration may be slow ![]() Still, I plan to 'restore' it, for want of a better word, and I will document as much as I can in pictures, and component values,(for those, like me cant read DMs schematic). Until recently when with the help of StephaninMelb I hadn't a clue! Hey I was a toddler in the 80's. I know Dean Markley doesn't make amps as their main product, but this is a decent foray into that world.I have been researching the Dean Markley t120R i own, since I inherited it and no little about it. It's a pretty cheap amp and a good price for a practice amp. However, I get good use out of it when I'm just rehearsing on my own, working on scales and ideas. I miss the great breakup of a good amp when I'm playing this amp, so I'd have to say I'm a little disappointed. I'd say that the midrange is a little too loud on this amp if I had to critique the frequency curve at all. So as long as you keep this lower, it'll be great for blues and country, as well as lighter rock stuff. The drive channel has a good sound at the same volume levels, great at low volumes but horrible louder. It doesn't have good distortion like most good tube amps do once they start to break up. When you crank it, though, it starts to break up and it's a little too much distortion to deal with, honestly. That's why this is such a good rehearsal amp. The clean tones have a lot of depth and character to them, and they really sing. This amp sounds pretty great at low volumes. The manual is pretty barebones, there's not a whole lot going on that you couldn't figure out yourself. The footswitch makes using it much easier. It is, however, more than capable of being a practice amp, and being a good rehearsal amp for smaller, quieter bands. I would say that it's probably not going to cut it for gigs, as it's not quite loud enough. Getting a good sound out of this guy is not the easiest thing in the world, but it's manageable. Channel switching and reverb are both capable of being operated by footswitch. It has a three-band EQ for both channels, as well as reverb. This amp has 50 watts of power delivered to it, and has two channels (clean and drive). Strengths: Good clear sound, a body double so convenient return and a double entry to play and sing along! first experience, so it deserves to be reviewed, but not for the Blues, not the masses send it, so for the rock either. I remember I went to a pretty good song!įirst amp. The sound is really too christallin blues and even a footswitch drivers in this hard enough ear. It was my first amp to play the Blues at the harmonic and really is not for that! The channel is very saturated and rocky but too grunch slammingĬlear channel is quite faithful to the acoustic ![]() The sound is not as powerful as advertised and the settings are sensitive Amplification transistor body double (1 X HP 12 2) (the photo does not show the second box connected via jack) ![]()
