Swapped out the 30 yr old AlCap capacitors for the Audyn Q4 on Wills recommendation (along with a ferrofluid change). What a difference, added so much more definition and clarity. Very impressed. Audyns are a fair bit bigger size wise but fitted easily enough on the board and the access aperture on the TDL Studio 1's.
Good quality, fast postage, perfect! Thanks
Can fault the service and you always seem to have what others don’t, this can be critical when your hobby involves restoring vintage hifi .
Excellent driver and superb service and advice from Willy's hi-fi. Would certainly recommend and I will definitely be using again. Super fast delivery and great prices
They offer great advice genuinely helpful and knowledgeable.
Excellent service.
Very happy with this replacement part, especially once id fitted it correctly!! Sounds great so know where to go when the other one fails. 👍
