That's really encouraging- it goes to show that some time, effort and small expenditure really can make a difference. I don't think it's a bad thing to make competent improvements to old sets like this if it makes them more usable and effective- not least because it means that more are likely to be kept for longer and are less likely to be thrown away as no good, or stuck at the back of a shed to rot.

In the UK and USA at least, there were many excellent communications receivers from WW2 that appeared on the surplus market for a long time after the war for a fraction of what they cost the taxpayer and they still continued to be effective for decades- I'm sure that this must have made it difficult for makers of new receivers like this to make something that people would buy without cutting quite a few corners.
