MERIDIAN: Their 101, 103 & 103D amplifiers revisited and …. the elusive 102

Gentlemen – what can you tell me about the Meridian 101/103D amplifiers from the 1970s? They look like a bargain on e-bay. The 101 series preamps are tremendous value on the used market today fetching ridiculously low prices given the clarity and transparency of the reproduction. They use DIN plugs throughout, other than later versions […]

EWA: Alan Elsdon / Colin Wonfor – What is it that causes output transistors to blow?

Dear Colin, Generally speaking, what is it that causes output transistors to blow? Do they tend to die a natural death? Bad drivers? Emitters? Problems with the rectifier circuit? Assuming there wasn’t shorted speaker wires or excessive moisture. The amp bias and the +/-77 voltage was fine before they blew. It happened on power up. […]

EWA: Alan Elsdon / Colin Wonfor – Replacing ceramic resistors in Monitor Audio GXC350 speaker

Hello Colin. Great series so far. Thank you. A little background info: I own a Monitor Audio GXC350 centre speaker and have discovered the midrange driver produces no sound. Swapping the driver over with one from a GX200 confirms it’s ok. A volt meter shows there’s no output to the midrange driver which points to […]

EWA: Alan Elsdon / Colin Wonfor – Passive preamps, the downside.

Hello Colin. I’m sure you’re aware of passive preamps such as Music First. I don’t think you’ll sort person to comment negatively on a particular brand but I do wonder what your views are on such devices? Not wishing to anticipate your answer, I’ve listened to the MF device and been very impressed by the […]

EWA: Alan Elsdon / Colin Wonfor – High quality “audiophile” grade sub panel

Dear Colin, audiophile grade sub panel and breakers? Do you know of a high quality “audiophile” grade sub panel? I read an article from someone in the audio industry where he mentioned having used a GE industrial grade 225 amp panel with a super duty silver plated copper bus bar and bolt on low noise […]

EWA: Alan Elsdon / Colin Wonfor – An EWA active speaker perhaps?

Hi Colin. Have you ever considered getting involved in active speaker design? From what I can gather, this is quite a complex task to get it right which is why, apparently so few companies get involved. I’m wondering if perhaps at some point in the future you might consider taking a good quality passive speaker […]

EWA: Alan Elsdon / Colin Wonfor – Top resistors

Dear Colin, Top resistors. Many threads with opinions on boutique coupling capacitors, but very little consolidated information on the sonics of resistors. Do you care to share your thoughts on the attributes of their favorite brands & types for specific tube and SS applications? How much of a difference does a good resistor make? My […]
