Myring Wiring - Making the World Sound Better
 

Avalon Design Repair Centre


This page still under construction in November 2020

(some of us have real work to do, including Avalon repairs).

There have been changes at Avalon Design. You will notice that some products have been discontinued from the Price List and there are different arrangements for (in the USA) accessory purchase through Sweetwater and service provision through Audio Rehab. I will be updating this page from time to time with the latest developments. Don't worry - your Avalon product is still supported and I'm still working as normal during the Covid-19 lockdown.

Breaking news!

New product sighting at NAMM January 2020 - see YouTube interview.

Warranty repairs

Studiocare was the last appointed UK distributor for Avalon Design products, announced in an October 2014 article in the blog section of their website.
They set up a 'microsite' for further information about the product range, and their sales site is here, with prices shown. Looking at it now in November 2020, the site shows some items and accessories and the Avalon Design site says "Please contact the factory..."

You can ask about warranty service using "avalon at myringwiring dot co dot uk". It's always helpful to know where you are located and the serial number of the unit, plus the date and place of purchase.


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. Tell me where you are located and the serial number of the unit in question.

Repair Parts

I keep some repair parts to avoid the delay in shipping from the USA 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. Responses from Avalon Design to parts enquiries had been slow but improving until the Coronavirus lockdown. The factory was in lockdown, effective 20 March 2020, and after a brief let up, they are now in limited lockdown again. Because of this, priority will be given to functional repairs over cosmetic replacements.

A note about tubes for the VT-Series

I don't sell the 6922EH tubes used in the VT-737sp and VT-747sp. If you want to try replacing tubes yourself, 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, or subjected to some other enhancement, but these procedures do not always reveal excessive noise, microphonics and distortion. These parameters can only be assessed in the intended application. I have found the current 6922EH production, as supplied in the official sets, to be very consistent, generally having low noise, low microphonics, low distortion and low reject rates.

To illustrate this, I note that two VT-747sp recently repaired had been fitted with some 'unofficial' tubes: in one case there was a crackle; in the other, two of the tubes were microphonic and rang like a bell.
