  6. Item: Matched pair NOS Amperex Hammond 12ax7 tubes Location: PErth - will post within Aus. Price: $325 Item Condition: NOS - As new Reason for selling: surplus Payment Method: EFT by mobile Extra Info: Made for Hammond organs by Amperex in the Herleen plant in Holland in 1967. These were NOS when I bought them. Tested 72/73 and 73/73 by original owner on a Hickock (min good is 50/50) . I bought four and currently use two of them in my phono stage. I’ve only plugged these two in to test for this sale and confirm they play beautifully in my setup. I was keeping them as spares, but better they go to a good home and get used. They have a big, luscious, sweet and slightly warm sound IMO. I absolutely love them. Photos: Advertisements without photos of the actual item will not be approved.
  7. Item: Vintage Siemens e83cc (12ax7, ecc83) triple mica tubes x 4 Location: Perth WA Price: $390 for all four tubes. Free post within Aus (only for purchase of all four). Item Condition: test NOS, low noise Reason for selling: too many tubes Payment Method: EFT, PayPal Extra Info: These are the much sought after ‘triple mica’ Siemens 12ax7 Tubes made in the Siemens & Halske Munich plant in September 1963 according to the acid etched codes on the glass. The e83cc was designed to be a very quiet, long lived and and anti-microphonic tube. These four are indeed extremely quite, transparent and crystal clear in my phono stage and preamp. They tested NOS when I bought them about 6 months ago. I’ve put a couple of hours on them at most. The test results provided by the seller I bought them off are as follows (and marked on the boxes - see photos). Tested on an Amplitrex AT1000 Sr.No.261106 T1=Ia=2.0ma Gm=1500 T2=Ia=2.0ma Gm=1500 Sr.No.206028 T1=Ia=2.0ma Gm=1500 T2=Ia=2.1ma Gm=1500 Sr.No.768632 T1=Ia=2.2ma Gm=1500 T2=Ia=2.3ma Gm=1500 Sr.No.769203 T1=Ia=2.1ma Gm=1500 T2=Ia=2.2ma Gm=1500 Photos: Advertisements without photos of the actual item will not be approved.
  8. Item: Western Electric 420a >> 12AX7 or 12AT7 Tubes with Adaptors NOS - 3 pairs Location: Sydney East Price: $135 per pair plus postage. Without adaptors $110 Item Condition: NOS perfect Reason for selling: NLR Payment Method: Pickup - Cash, Paypal, Bank TT For sale are these great sounding Western Electric 420a /JW 5755 NOS tubes which when coupled with an adaptor (included) function as a superior 12AX7 or a 12AT7. They are much better in many ways than other 12AX7s I have tried, including: Mullard, Telefunken, Amperex and any Chinese tubes (Psvane etc). The most obvious improvements came in bass drive and resolution. Greater timbral information and texture is evident throughout the mids and bass. Glorious textural information not experienced with any of the tubes mentioned above. Dynamics are scary. Clarity is excellent. Designed for very low microphonics… The WE 420a "features special cathode springs which reduce microphonic response. This characteristic is controlled by a "microphonic stability" test for balance in which the tube is tapped at shock levels of 400 - 600G." Very fine wires (springs) just above the top mica can be seen in pics. The specs are a little different from a 12AX7 which has an amplification factor of 100, 12AT7 is 60, and the Western Electric 420a is 70. I have tried the Raytheon 5755 equivalent and as expected the Western Electric sounds better and is reliable (the Raytheon is not). WE is the real deal! I guarantee these will be keepers irrespective of the tubes you are using. Happy to demo against Mullard and Psvane or your own tubes to serious buyers.
