You can, but you will need to readjust the focus controls, as the focus voltage for the 07MP are different than the MSP.

Thank you, Curt. Are you a little more detail how to do it? I have all parts of the VPH 1270 addition to sf41-15 the PCB board. What can I put into 1272? What do I do with tension? what do I do with the focus?

Most boards will swap out. The focus controls will need to be tweaked, but the tubes transfer between the sets.

Just adjust those focus controls in the top right corner of the above pix, do not touch the screen/G2 controls.. for now. If the focus control ends up being out of range (it shouldn't), then I should have some near new 07MSP tubes here, red and green anyways I think..for cheap.
