Calibration Services
<under development>
Valve matching & characteristic reporting, Send or bring in your pairs or quads.
- For ones I sell I aim for just 5% variation in plate current.
Avo VCM calibration and repair, incl most meters to MkII-MkIV, Ct-160 and 163
- The MC magnets in the avo meters can loose gauss and make readings less by 20+%, Opamps cure this.
Standardizing valves for your own valve tester calibration
- I'll supply a valve tested by dedicated dc supplies and dead accurate 4 wire kelvin meters with slope data
Specialist Digital LCZR testing to <0.25%
- Need your chokes measured?, your capacitors ESR determined?
Supply of calibrated R's & C's for your own calibration tests
- Wanting a 10.013 ohm resistor or a 151.252pF cap to check your meter(s)?
