In Reply to: RE: Help identifying Shindo nos tubes for Montrachet posted by montaldo on February 06, 2017 at 04:46:08
Thanks for all the input. Another knowledgeable friend agreed with the opinions here. RTF they are. I had them tested on a B&K dyna-jet tester and they are all good. The one that briefly lit up in the Music Reference RM-9 amp before it's tube fuse blew is just as strong as the others (90), despite what that 1 second did to its appearance. No shorts in any of them.
Given that these are Shindo-supplied tubes, am I right that they were carefully selected and matched? I hear all kinds of things about Shindo's selectivity. Does this impact their value? I imagine the discoloration in the one tube will hurt the value a bit, on the other hand.
So should I ask $50-75 each or is that too low? Unfortunately I paid $500 three months ago for this set, including the input tubes that are probably not worth much.
That it blew A fuse in an RM-9 is not a critical problem - the fuse was installed for two reasons: 1: to protect the amp from a run-away bias, and 2: to deal with 'Lint Shorts' where a piece of lint or other gets caught between the screens or plate and screen of a power tube .
This is more common among some tubes than others- though I have had my fair share w/ Siemens tubes in RM-9s...
They are wonderful tubes, and I keep at least one spare set for my amp.....
50-75 bucks for each is not a reasonable price! on e-pay (europe/germany) you would find good used quads for 120-150 € or US$. shindo´s RFTs can not be wonder tubes. he has/had to take from old stock as any other vendor too.
the RFT EL34 is known as a great tube which can safely take high anode voltage giving a neutral, tight, "rocky" sound and good midrange. highly recommended among guitar players but meanwhile among audio enthusiats also. my experience is that the solution compared to mullards is lacking a little. but just a little...
