Vox guitar organ oscillator transistor replacement
Hi,
I'm repairing a Vox guitar organ and have an open circuit transistor which is a U15703. I can't find anything online about this transistor, can anyone recommend a suitable replacement? Many thanks. |

The VOX Continental organ used 2N3708 transistors in the tone generator. The Guitorgan is similar.
