@@RadiogenesRather than wait for your set to fail (we hope Not) , buy one thats 100% faulty ie blown synth from a dealer and bring it back to life as nothing to lose.
Yes, unless your fit to service them or know (with proof) radio is serviced & stable on tx Id avoid. Failures are beyond the boring & outdated advice on forums of change the caps in psu & synth. A Lot more is failing now in them. Ive serviced/modded more than a few. A nos unissued one wont last either without intervention. Just saying. 73
