Default Re: Trio 9R-59 Shortwave Receiver

Tony, congratulations on that painstaking rebuild. I can just imagine your delight when the set came to life after all that work.

I have the later DS version which took some work to get it fixed, and it too suffers from the same tuning drift problems that have been mentioned. The HT voltage stabilizer makes no difference at all. After much investigation, I discovered that the set is actually very sensitive to temperature changes and mains voltage fluctuations, and I think it’s more to do with the heater voltages than anything else.

Despite all its failings, this set is still strangely appealing, and its performance on Medium Wave alone make it a good set to have. Well done!
