<HTML>List, I have never had the opportunity to tune one of these.  Any that I have ever seen (just a few) were too old and deteriorated to be serviceable.  I'm glad, however that now there are some constructive answers to questions about them. When I first joined this list a few years ago, someone asked an honest question about them and got the most condescending answer possible from someone who is now, thankfully gone and hopefully will never return.  The phrase was "Birdcages are for the birds!". When I tried to write a constructive answer, this guy went ballistic.  Take it from me that nearly anyone who talks the way he did is interested in one thing only:  to make everyone think that he (and sometimes a she too) is God's gift to the piano tuning profession.  You'll never get any useful information from this kind of person.  You'll only be made to feel like an idiot for not calling virtually all pianos a "PSO", "junk" or some other insult. When you have a few of these type dominating the list, there is nothing to discuss because it is presumed that everyone already knows everything.  Therefore, a discussion list for piano technology rarely gets involved with any details, there are only one line jokes and off topic anecdotes.  Actually answering someone's question with detail and purpose is unwelcome. I sure am glad those days are gone and that what appears here presently is worthwhile.  In my view, there are very few pianos out there which are categorically not worth servicing.  Most worthless pianos are already gone.  The recent topic of the Lindner is one exception.  They were built mostly of plastic which biodegraded after 15-20 years to the point where the material just crumbles in your hands. While there are a few technicians who limit their practice to high quality grands or only do concert or university work, the vast majority of us work on a mix of pianos of all types.  The kinds of questions and comments that come up are what keeps this discussion going and interesting. I'm glad to be part of it and the old pecking order is long gone.
