Melbourne Audio Club Wed 18 April

The presenter is going to be John (Hifi exchanges John) and I’m sure it will be a good meeting. He’s bringing my favourite Tannoy PA speakers, make an offer after the meeting around $1500 and you might be lucky.

Sat 14 at Hifi Exchange Valve testing, CDs on sale, free sausage sizzle

A reminder that next Sat there is a sausage sizzle (with decent sausages) as well as Ian and Bev from Rockian will be there with the usual selection of CDs and plenty of new vinyl,and here is a quote about the free valve clinic:

OK we’ve stolen this idea from McIntosh back in the 1960s and 1970s but it’s a good one so we’re going to go with it.

Saturday 14th April we will be have a free “Check Out Your Tube Amp” clinic for all customers.

open to all – you don’t need to be a regular customer or even have bought the item from us.

Our tech will be on hand to give your amp a run over as follows:

1. Check bias current in output tubes..a good sign an amp is healthy

2. Check output tube life, performance and matching

3. Check amp for even frequency response, noise, distortion and, if you are brave, maximum power output.

4. Preamps can be tested for RIAA phono accuracy.

If you buy tubes on the day we will bias your amp free of charge.

Note- tests will be performed on power or integrated amps using up to four octal output tubes only – EL34/6CA7, 6550, KT88, KT66 and 6L6GC.  This includes ALL Leak, Quad, Radford, Pre 1980 McIntosh, Marantz, Dynaco and most chinese amps except SET models.  No direct heated triode amps and no amps with more than four output tubes due to time constraints.  (If unsure ask in advance)
