You have a much higher chance in getting those Cheviots, as you are based in London.

Perhaps Shane, but it will be up to Geoff and I'm sure many people will drive vast distances for the Cheviots.

But having said that - Geoff if you are selling I can come around first thing in the morning to pick them up.

Cash in hand :lol:

But if I recall Geoff you may have already given first refusal to someone else.

Idiosyncratic looking things. I've seen them in the flesh when I used to visit Geoff.

They're not at all bad. EL34 sound similar to Radford STA25. Very unusual styling.

What is their output? 30watt
13-12-2018, 22:32
walpurgis

15 watts. But they boogie and drive the Tannoys brilliantly.
13-12-2018, 23:00

Only 15. Thought they'd be more. Would be enough tho

I was bored. So, the latest walpurgis bodge-up!

A pair of empty Rega EL8 cabinets'

http://i63.tinypic.com/16jrbyw.jpg

Some rather nice 'drop-in' five inch full range drivers and black acrylic blanking plate for the tweeter hole..

http://i64.tinypic.com/vfl1ms.jpg

http://i64.tinypic.com/24o53kl.jpg

Some original type terminal plates.

http://i63.tinypic.com/1so0eb.jpg

http://i63.tinypic.com/dcfr5c.jpg

Everything fits. Now I just have to wire up and screw everything in.

Just a bit of fun, but it'll work fine.

Been playing with the little Rega boxes. They look a bit lost next to the Tannoys, but sound better than I'd expected. Reasonably full bodied, clean and no lack of detail. This is just a temporary rig-up, soon I'll get around to bodging them properly! :)

Yes, I know the Tannoy grilles are a bit dusty.

I keep looking at chunky Japanese integrated amps on ebay and getting tempted, then I remember I've got one :).

Well done Dan I've been through the bargain hunting cold turkey too, feel better for it but I now throw a few hundred into occasional purchases while I would have thought that frivolous a few years ago. The system is sounding better for it mind you :)

Just trying out my Chinese 5" full range drivers. I bunged them in some spare small Philips reflex boxes for a listen. The sound is way better than anticipated, very transparent and detailed with none of the upper end sizzle I usually hear with twin cone drivers. I reckon a compact 1/4 wave TL box could be the way to go with these.

Are those going to become your main speakers once the Tannoys go?

Probably not, I have rather a lot of speaker options.

Delivered cost for a pair from China worked out at just over £100.

There's a listing here: https://es.aliexpress.com/item/Aucha...OrigTitle=true

There's a quarter wave horn type enclosure design here if anybody can make sense of it. Not what I'll be using.

Looks a bit like the Hi Fi News Paraline design from the 60's, was a great sounding speaker using an 8" Elac unit (8N148 or 8N185). My pair made a terrific sound from a 1 Watt amplifier that I constructed.

My inclination is to go with something like the Daline enclosure. Coincidentally, I found the original Daline magazine articles and designs last night whilst going through some old papers.

The Paraline was the predecessor of the Daline. I still have the Dalines (B110, T15 and Coles 401G), unfortunately, I sold the Paralines many decades ago, wish I still had them.

I suspect that the Paralines might be a better fit for your drive units.

Yes, that's it, I used mine with them standing on end, more like a conventional speaker. I've found the Hi Fi News constructional details on my PC, available to anyone who wants them. Also the postscript.
23-01-2019, 09:41

It's a quarter wave horn with constricted port. Similar to some of the Frugel designs.

What is not shown in the sketch is the strategically placed damping material. This is quite important.

I can upload the constructional detail to Flickr if anyone wants.

Hmm. I'll have to sit down with pencil & paper today and work out the cabinet design for the forthcoming speakers.

I have some basic driver parameters to work with and will come up with something suitable. At the moment I'm debating on the choice between a quarter wave constant width acoustic column or tapered transmission line. The acoustic column has some advantages, but is larger.

I'm also wondering whether to go for pre-veneered board or plain and do my own veneering. I'll probably go with the latter. (no, I don't want to use a piano lacquer finish, I can do it, but it takes ages)

usually think the pre done stuff can chip and your left with an issue, while doing it at end you'll get a better job

You're right Grant. I have used both in the past.
24-01-2019, 12:46

You could go with the Capel design.

I wasn't keen on the frugelhorns, I'd avoid that one personally.

This should be a link to the Hi Fi News Paraline design constructional details.

I don't have a link and I can't find any reference to it on the internet either which is odd. It was a transmission line using a full range racetrack driver designed by VJ Capel - the plans were in those little books you used to be able to buy from electronics shops. When there were electronics shops.

Oooh. What's this part of? I think it has Pass 2.0 written on it somewhere :).

http://i63.tinypic.com/esqlcg.jpg

On its way from the far east. Will have to wait a little while for it to get here.

Has three switchable output levels. Could be handy.

However, he has declared the TPA3116 unit "embarrassingly good" and the equal of the Creek in his system. Like myself, he has now ordered a second one. They are that impressive!!

If you own moderately sensitive speakers you really deserve to hear what these little things can do and at around £25 including power supply, why not give it a go?

I can believe it! It is embarrassingly good. I thought I might try one for myself, so ordered one on the fly for £19.99 inc postage from China.

Didn’t really have a chance to listen until I plonked an old NUC system power supply into it and plugged in the Allo Boss and MS 400’s expecting a fairly ‘meh’ sound.

Even on the short listen (30 mins) to a variety of ‘usual suspects’ tracks, it is astonishing value.

Enough to make me want to explore routing more sources through it.

Wondering what would be the least expensive/disruptive option to connect more than one source, a simple RCA switch box maybe?
