This power supply needs for testing tubes with other then 4V, 5V or 6.3V filament heating.

Excellent working (as new) conditions. Used only to test-match some tubes for my audio gear - ALTUM tube phono stage, tube pre-amp and 2x S.E.T. valve mono blocks (as per reference photo).

Please see the photos showing the test process of some 6SN7GT tubes.
Please note: This is not like “automated, plug&play” emission tester.
It’s similar to Orange Amps digital valve tester VT1000, Amplitrex AT-1000 or MaxiMatcher, but provides fully manual and not automated measurement process. Measurements : transconductance , internal resistance and gain are possible. But to operate this tester you must have some valve, tube theory knowledge.

Ordering such tester from the website would cost $684NZD incl shipping + $156NZD duty fee = $840NZD
Wanptek KPS305D another $80NZD
So the total cost of the whole set would be approx. $900 NZD - my loss your gain :)

Just FYI:
1. The website to download almost any of the electron Tube Data sheets in PDF:
2. IMHO: the most benefit of this pulse tube tester in compare to other vintage testers on the market, is that you don't ever have to calibrate it.

Should you have any questions please ask.

NOTE for “watchers” - $499 is the bottom price and I won't let it go below this point :) or miss out... no post auction offers will be made or considered.
