Warranty repairs

On 06 October 2014, Studiocare published an article in the blog section of their website. It announced their appointment as UK distributor for Avalon Design products.

Studiocare have set up a 'microsite' for further information about the product range, and their sales site is here, with prices shown.

You can ask about warranty service using "avalon at myringwiring dot co dot uk". I have received some warranty referrals from Studiocare, so the new system seems to be working.


Repairs on units out of warranty

For the usual no nonsense, any hour of the day or night, service you have come to expect, please use "avalon at myringwiring dot co dot uk". I have been operating the official repair centre since 1996.

Repair Parts

I keep some repair parts to avoid the delay in shipping from Avalon Design on a 'job by job' basis. I don't have retail sale facilities. At present, it is not known who will be responsible for parts sales to users wanting to do their own repairs.

A note about tubes for the VT-Series

I don't sell the 6922EH tubes used in the VT-737sp and VT-747sp. They are retail items which you can buy in sets from Studiocare or your local distributor. I supply and fit tubes only as part of a repair when I can test them and burn them in.

Customers have been tempted to buy exotic variants of the 6922 from online suppliers. These tubes may have a claim of being tested on one of the popular tube testers or they may have been cryogenically treated, but these procedures do not always reveal excessive noise and microphonics. These parameters can only be assessed in the intended application. I have found the current 6922EH to be very consistent with low noise, low microphonics, low distortion and low reject rates.

Product information

Details of all products, and some handy trouble-shooting hints can be found on the Avalon Design website.
