Tube DIY Asylum: Re:"The Amity, Raven, and Aurora" by Lynn Olson by cheap-Jack

Hi Lynn.

You highly recommend TV damper diodes for use as audio HV rectifiers.
Please elaborate how good they are sonically as compared to conventional tube & SS rectifiers. I would very much like to try them
in my DIY all-triode projects.

What exact no. are NOS 6C*3 & where I can pick them up cheaply? I have hard time to locate Svetlana 6D22S, too. Please tell me. I need
some of your tried-out circuits using these TV damper diodes. Please
expedite. Many thanks.

I read your "Philosophy", & gladly know where you came from. As a technical writer, you should deserve some respects from the readers here, including yours truly. I like the pretty down-to-earth way you
pen-address the technical issues, making them so easy to apprehend, even for laymen.

While I would not dispute your philosophy of "tastes are very individual, and I design to please myself" (it sounds very similar
to Sakuma-san's), there is always a common goal of reproduced music:
closest to the "real thing" - live music. Of course, how close could one's rig go towards nirvana is another story, & it is always the momentum for carry-on upgrading.

My philosophy of audio reproduction is: "simple nothing is better than
inadequate something" - straight line concept. Trust me, I have proven it, with my DIY gears. So, you will have hard time to sell me
the idea of better sound by inserting transformers in the audio signal
passage. Surely, every design must have its own rationale. The bottom
line is how it sounds. I indeed look forward t auditioning some of your brandchilds. I am even tempted to visit Sakuma-san's restaurant-bar near Tokyo, to audition his transformers-loaded handcrafts as I will be on business to the Pacific rim this fall. See if I can squeeze some spare time to pop over there. Besides, I miss bigtime, Akihabara, Japan's electroncs-only town, & the largest electronics & home applicances wholesale-retail outlets in the world! Only some 20 minutes from Tokyo by subway.

Until my very picky ears okay the "long-live-tranformers" theme in whoever's tube designs, 'iron goods' is still not my cup of tea.

Have you by chance read my post on my audition of Audio Note's "system
of the millennium" whereby "Kegon", the 2x17-watt only, 4x300B power amp alone, asked for USSD128,000! This amp, designed & handbuilt by its founder, Kondo-san in Japan, does not use any input or interstage transformers. It sounded awesome! Please check up my post "Quiet enclosures" in the Tech Square asylum on 9 Sept. #65.95.90.147.

Constant current source (CCS) is a popular tube & SS design in Japan
for decades. You can find plenty of similar solid-state CCS designs
in many DIY tube-project journals in Japan, including the most established historic publication: "Wireless & Experiments". Surely,
CCS must got its tehnical merits. How good it sounds is yet for me
to appreciate.

YOu should NOT blame UL in saying you "aiming at credit or commercial
something". You are an equipment vendor & you are promoting bigtime
your "all-transformer-coupled, all-triode amps". This is your very upfornt business agenda in front of everyone's eyes here. He is only
stating a fact.

Whether you have used AA as your products marketplace is for the moderators to find out. I indeed somewhat admire UL's upfront "what is
fact is true" attitutde. His taking on you reminds me of Martin DeWulf, the owner & reviewer of 'Bound for Sound' on-line journal, an 'old school' type e-publication, which uniquely does not take any
advertisement from equipment suppliers. He dares to spit in the eyes
of whoever whom he finds out to be up against consumers' interest.

Good listening
