  1. Maybe an additional note re: vintage tubes. There’s mention of the internal construction but I believe the glass used is also a factor affecting sound of the tubes. In commercial, industrial use, glass in valve is just what is available in technology of the day. But in audio, that has quite an affect on sound quality. eg if u were to compare modern tubes like EML, they tend to use quite thick glass and the sound is generally firm, sturdy and ‘grounded’. Chinese valves tends to have a ‘ring’ to them. 20’s valves such as globe 45 sounds much more open than modern ones and the glass tend to be thinner because of glass making technology of the day. If one were to tap on the glass, u can hear the glass characteristics. Obviously glass quality is just one of the factor, there’s also the shape and size relatively to the other components and the extent of contact (mica) etc.
  2. Agreed with Red on the 5R4 potato masher. They are tough as hell, can drop them on the floor and still be ok. Audio Note use them with their 845 amp not because of sound quality but because they are robust! Likewise some of the triple mica tubes are necessary for fighter jets but not audio.
  3. I have a pair of Mullard 10M standard 12ax7 (under international corporation label if anyone is interested.
  4. Try packing it yourself…get foam and cardboard etc. Pack and send is hopeless, no clue how to pack properly. Get a courier via Transdirect..
  5. Did u get in touch with Bryan at AudioNote in Sydney. They distribute Takatsuki and the prices usually reasonable?
  6. Further information: For sale is an Oswalds Mill Audio Parallex PL519 amplifier, come with separate power supply. The chassis is solid dove tail jointed Philadelphia walnut with specially cut slate top. using PL519, a television sweep tube, in ‘screen’ mode as OMA described it, the tube is being used in triode mode. A low powered tube amp best suited to high efficiency speakers 95 db plus, in particular horns. OMA’s description on their website: https://oswaldsmillaudio.com/parallax OMA is renown for the design and beautiful workmanship. There aren’t many reviews online because Johnathon of OMA do not like audio reviews. There are some info on YouTube about OMA. The sound of their horn system is jaw dropping. The sound is natural, open and musical. The current retail price for this amp I believe is about $30,000USD, more than $40,000AUD! OMA never publish their prices. They have put their prices up massively in the last ten years. I was told by OMA that their phono stage (ex pre) alone is now 30,000 plus USD. I am happy to accept reasonable offers. I am merely trying to recoup some of the cost. I bought mine from a US dealer of OMA a few years back. I also have the phono pre but that’s not for sale. A pair of RSD PL519 will be included as well as a pair of rare Telefunken PL519. This is an earlier version of the amp without the built in volume control.
