In Reply to: RE: We keep hearing all this what's the best tube amp lately. posted by Michael Samra on December 10, 2014 at 03:06:35
Is it because it can't (for what reason) or that it would be too cost prohibitive? Thanks.

Two issues with the "iron"
1: age
2: chemistry -
the first can be addressed if you are young enough and can wait -
the second is a bit harder to address, because it is a 'scale' process.
The chemistry of the iron being produced today is different, and getting a run on "E-I" laminations produced would be prohibitive...
There is plenty of great iron out there today and they spec out fine however,if you want the exact iron that the Citation 2 has or the Mac iron, I don't think there is a comparable replacement for those amps that you can just go out and buy.

Its the PCBs they used in the potting compound
Magnequest has original prints for many older transformers. Part of transformer winding is an art: precise wire placement and wire tension. Most windings are tensioned by pulley with a weight attached.
Little known facts focus on even smaller differences in materials. Older trannies used paper separators, and different wire insulation. Supposedly newer material is electrically better but the sound is not necessarily the same.
In speaking to a designer who designs his own OTs, his complaint was that it took him a decade to find a winder who would follow his specs exactly.
On the other hand, modern winders abound
Dave Slagle is just one such winder. Still it takes time and experience to become tops in any field. Word was only one individual wound the OT for the Marantz 9's. Takes a lot of practice and repetition and observation with experimentation. If you don't have a large company to back you the stack of dead iron can grow quickly
comes close in quality?

I wonder what variables along with state and quality of restoration work done to vintage tube amps most effect their sound.Differences in circuit design & tube types between the Mc240 and the Mc275 comes to mind.Winding output transformers seems to be cost prohibitive and a lost art as pertaining to new amps.
For 40 years my father worked in a factory that made transformers.They would hand wind and assemble them. Even hand paint (damn auto correct) them.
I don't think many people know this. But a transformer is almost entirely made by hand. At least the bigger ones are.

"They would hand wind and assemble them. Even had pain them."
Did that last part happen when someone's hand got pulled into the winder pulley?
sorry, couldn't resist.
Sorry, after I read that post I LOL. Yeap,the old auto correct did me wrong!
I'm not saying our fine education system is at fault either. Ironical that one can achieve a doctorate and still be unable to spell and construct a sentence.
Did you see the Asylum post (link below) regarding some humorous Auto-Corrects?
Makes sense. Thank you.
