If you are looking to test your precious valves and you don’t have the equipment, I can now offer this service for you which includes:
- Valve health check
- Valve bias point measurement (Ia, Is @ Va, Vs)
- Transfer curves
- Characteristic curves
- Microphony (optional)
- Distortion – THD (optional)
- SPICE model for triodes (optional)
Some examples of a lovely EL34 Mullard tested on request:
My fees are very competitive and this service is worth if you are looking to sell your valves or match them.
Terms and conditions:
- Price varies on level of testing and amount of valves
- Postage is not included and depend on your location. I’m in London, UK so you can easily estimate the costs beforehand.
Update – August 2021
My apologies but due to pandemic and lack of free time, I’m not offering this service anymore.
Thanks again for testing my vintage output valves for sale recently. All went smoothly without a hitch and they are back safely along with very comprehensive data. Your friendly and trustworthy service greatly exceeded my expectations.
Thanks Daniel for your feedback. I’m glad this worked out for you
Cheers
Ale
