. There is an old RM-9 on the gon for 2 grand. Would this be worth pursuing ?
Used asking prices do vary widely, and some listings are pricey, but I stand by my previous comment.
No argument there. There are many factors to take into account for used equipment. Especially used equipment such as the RM-9, since many of them tend to be a bit older. Besides age and overall condition, you have the number of owners, possible modifications, hours of use on the tubes (perhaps additional sets of tubes). My point to the OP is that the used model he is looking at may not be as far off from the norm as you were leading on. Even some of your own examples are right there in the same range.BTW, I have no affiliation with the owner of that current RM-9 for sale whatsoever.
There's a bit of confusion here.The RM9 amp on AG now that OP is inquiring about is a mk1. My point is that mk2's can often be had for the same price, even cheaper.
Used asking prices do vary widely, and some listings are pricey, but I stand by my previous comment. If you are patient you can get a mk2 in the 1700 to 2000 range.Here are three recent examples:http://app.audiogon.com/listings/tube-music-reference-rm9-mkll-2013-08-07-amplifiers-93601http://app.audiogon.com/listings/tube-music-reference-rm9-mk-2-more-please-read-text-2013-11-22-amplifiers-14304http://app.audiogon.com/listings/tube-music-reference-rm9-mkii-w-new-set-of-eh-el34-tubes-2012-12-09-amplifiers-55912Keep in mind these are asking prices. Actual txn price could well be less.On top of this, in past 18 mos I bought and sold my mk2 for $1500. So add these two transactions to the list.
In looking at those listings I see they are rather old ......
. Would it be cool to scoop this 9 and send it for updates ? Seems logical ? My old buddy Mike bought one ? Interesting ! He told me about the 38's ,,,, ha
Is there any sonic improvement with your hand wound transformers? Really worth the $1k expense?
. Roger ,,,, for God sakes ,, STOP MAKING SENSE ! Mods are not worth it unless you " hear " them and are " happy " with the outcome. So, the mod has to be benched and voiced and tried and trued. So if I bought this amp , can I get the up-dates done ? and the cost ? Or is it cheaper and smarter to buy new ! A 200 ?
Currently we are winding everything here, I have given up on outside winders who can't seem to follow my instructions. Outside winders have a variation in high frequency cutoff as bad as 2 to 1. In house we can get that down to 20% and I can do better than 10%. Although I supervise the winding how can I take a new person and expect him to do what I have been practicing for over 30 years? Here's an important difference. Since I designed the transformer I know what variations make a difference and what do not. It's a little like baking, each cake turns out a little different but the differences are far less when the baker knows what is important and what is not. When winding each transformer there are often decisions that have to be made as it is happening. I have a "exemplar" output transformer with the highest frequency response I ever obtained and no one has been able to match or beat it... though some do come close. Given the cost of most amplifiers today and that we are one of a very few companies that winds in house, I do think its a pretty good deal.
