Let there be light!!!
final JTM45
Today order the plywood cuts for the head cabinet, and the combo version with 2x12 (these not order yet).
I can´t be able to test sounding until bough the speakers

Re: Hello! building a Jtm45 and a 1974x
I ve got a question for the wiring diagram of the output jack and to connect the speakers.
i mounted with the manual.
My idea is to make an speaker cab loaded with G12M greenbacks 25w 16ohms 2x12, but could use 1x12 in each jack output. (in that case using the 2 speakers the switch would be in 8ohms'? and using a single one in 16?.

Re: Hello! building a Jtm45 and a 1974x
It all depends on how your speaker cabs are wired and what impedance each one has. If you have two 16ohm cabs, then you would set the impedance selector at 8ohms. If you have two cabs that are rated for 8ohms each, then you would set the amp at 4ohms. Always check the actual impedance of the cab after wiring the speakers by plugging in a speaker cable and taking a reading with your meter at the tip and sleeve of the cable end.

Hello! finally i tested de jtm with one creamback G12m 65w, the sound is amazing, now im making the cabinets for the head and the speakers.
The sound of normal channel is ok, but on hightreble i got some noise, (shielded or grounding issue), i could check.
When i plug the guitar and play, if i touch some metal surface (like door or window), i feel like a little static.
Tomorrow i share the sounding°

Hello! Finaly Noise Free in JTM. I detach all wires and de board and rewired, and resolder some joints. I move the OT far away from the OT, and rotate it, (I put it in wrong orientation the first time), I elevate with rubbers OT, PT, and Choke to try to cancel fields. Next saturday HAPPY new year
