I'll install it in Daffodil once the weather warms up a bit... Garage is currently like a deep-freeze 🥶
Beware the wrath of the lady scorned. You may find Daffodil finds an E for her model name and wields it toward your numb digits!! :-D

I believe there may be some interest in this item !! :)

Also towards the end of page 4 of this catalogue there are a number of audio equipment lots which may be of interest.

I've not gone back to vinyl yet and probably won't but I'm sure someone will want them. I remember the first 45 rpm record I saw, it was when I worked in London in 1954.

The Avo and other meter have gone apparently, they used to cost fortune but very few people want them now, you can slip a digital meter in your pocket but not so an Avo - unless you are a poacher. :wink: I only use mine for the car as the Fluke meter doesn't have an amps range.

Give me an AVO any day! I've finally reassembled mine and it's back in service now :)

Just done an ebay search for AVO meter, and found a nice selection;

I have a couple of them Jim but space and weight are a penalty compared with digital. My old Fluke 11, bought for a lot of money about 40 years ago is almost indestructible, although the display is loosing some of its surface but not obliterating anything yet.

I had a dreadful time trying to adapt to a digi meter when I first had one - but I'm used to it now. :wink:

A bit of amp. work today :) One of my Leak Stereo 30s died on its right channel...
leaks30.jpg
It's rarely used as it lives in my bedroom and partners a Leak stereo Troughline tuner... It only sees any use if I'm ill and confined to bed and that's (thankfully) very rare indeed nowadays :D

I do like to run both it and the tuner up on occasion to keep it in good condition. Something I do with all my vintage kit...

The fault was very quickly traced to a 'tin whisker' in T5R, an AF118. The AF11x transistor family are notorious for growing 'tin whiskers' and the quick and dirty bodge is to lift the screen wire. The whiskers grow and short either emitter, base or collector - or indeed all three - to the can which is grounded via the screen wire...

In this case I was able to successfully 'blow' the whisker using my AVO on high ohms range :) This is only a stop-gap until I source a replacement... The AF118 is a bit of a rare beast and has no direct equivalent. It's an RF transistor was an odd choice for Leak to use it as a pre-driver in the power amplifier section... Nobody can shed any light on why they did... Maybe Harold Leak got hold of a job lot that fell off the back of a lorry...

For a while I'd noted a bit 'crunch' noise when it was first turned on from cold... This problem was traced to leaky coupling electrolytics putting a bit of DC on the volume control tracks... A couple of new capacitors and all is now good...

Well done Jim - didn't used to get that problem with valves. :-D
