basstone Posted December 5, 2019 Share Posted December 5, 2019 Having checked out the SVT with the cab, I thought it would be interesting to try out this. It is a General Electric PA amplifier, made in 1935. 4 KT66 cathode biased output valves and rated very conservatively at 30W. It was my first amp when I started playing well over 40 years ago! My father had just bought a TV and cycle shop business and we found this old (even then) amp languishing in the loft. It needed a good service, jack connectors adding for input and output and a matching transformer for the 100v line output. It weighs nearly as much as the SVT and back in the day was paired with a massive 1 x 12" cab with a slate baffle from an old billiard table with 1 1/4" chipboard for the rest of the cab and a pine frame around the front, painted gloss purple! The cab is long gone but I still have the amp and it still works. The valves are all original except for the driver. I've changed a couple of leaky caps and added some new smoothing caps to help the originals. It's not as loud as the SVT but has a smooth slightly compressed sound. A peek inside for the tech minded. Very neat and easy to work on. 3 Quote Link to comment Share on other sites More sharing options...
stevie Posted December 5, 2019 Share Posted December 5, 2019 Ooh, that's a blast from the past. It conjures up expressions like Vortexion, Ferrograph and Reslo. It's actually got 'condensers' in it. And 85-year old electrolytics. Amazing! 1 Quote Link to comment Share on other sites More sharing options...

Indeed, funnily enough I also have a 1960's Reslo ribbon mic that was used with my Father's Ferrograph series 6 tape recorder 🙂 1 Quote Link to comment Share on other sites More sharing options...

stevie Posted December 5, 2019 Share Posted December 5, 2019 Talking of clamps.... Lidl are selling some neat, one-handed clamps, which would be a useful addition to the longer ones. Starts today - so won't be available for that long. https://www.lidl.co.uk/en/p/product-recommendation/powerfix-profi-one-handed-bar-clamps/p27850 If you're on the wating list for the next batch of kits, or if you plan building from the plans, I'd recommend you get yourself a set of the 150mm ones for £6.99. Cheaper than anywhere else. Quote Link to comment Share on other sites More sharing options...
Woodinblack Posted December 5, 2019 Share Posted December 5, 2019 All of mine, apart from the really long ones come from there. In fact a large amount of my shed contents come from the middle of lidl! Quote Link to comment Share on other sites More sharing options...

Very neat and easy to work on. No love for the Linear Concord? My first guitarist has one of those with a cab he made out of reclaimed wood from a wardrobe. I acnnort remember what guitarhe used but it made a wonderful noise. Quote Link to comment Share on other sites More sharing options...

Sadly id weighs more than my old Bosch 18V The 12V circular saw looks good though and the table saw and the clamps ............. oh dear I have an attack of TAS (Tool Acquisition Syndrome).

I have a cab that has been cut out to allow for rotation of the horn. Before I commit myself, I'll check it out later today. I seem to remember that it was not as straightforward as you might think. 1 Quote Link to comment Share on other sites More sharing options...

Isn’t the horn designed to be used 90 degrees from the way you’ve used it anyway? Quote Link to comment Share on other sites More sharing options...
stevie Posted December 5, 2019 Share Posted December 5, 2019 Yes, it is. And the horn is square. So in theory it should be easy enough to cut a hole in the baffle that allows it to be used either way. Quote Link to comment Share on other sites More sharing options...

What I mean is - if you don’t rotate it what you loose in vertical dispersion you gain in horizontal? Quote Link to comment Share on other sites More sharing options...
stevie Posted December 5, 2019 Share Posted December 5, 2019 (edited) Indeed. It's a 90 x 65 degree horn. On a PA cab, you'd want the wider, 90-degree dispersion in the horizontal direction, but turning the horn round gives you better dispersion directed at the player's ears when the cab's on the floor. You will lose some dispersion horizontally but it's not critical, and turning the horn round does make a difference when you're standing in front of the cab. It would also be useful to be able to rotate the horn if you're going to use the cab sideways, which isn't currently possible with the cutout as it is. So it's worthwhile finding out what's possible.

stevie Posted December 5, 2019 Share Posted December 5, 2019 Richard, I've had a look and I don't see a problem in creating another cutout at right angles to the existing one to allow for rotation of the horn. Quote Link to comment Share on other sites More sharing options...
RichardH Posted December 6, 2019 Share Posted December 6, 2019 Cheers - might be worth doing before the baffle gets fitted.... Quote Link to comment Share on other sites More sharing options...
stevie Posted December 10, 2019 Share Posted December 10, 2019 It looks like the next batch of cabinet kits will be ready next week. I'll be in touch with everyone as soon as I have a firm date. In the meantime, I've put together a pack containing all the screws, machine screws, t-nuts, washers etc. that builders will need. This will save you having to order them from different sources and ensure that you have the correct types. 3 Quote Link to comment Share on other sites More sharing options...
stevie Posted December 11, 2019 Share Posted December 11, 2019 I've updated the Parts List and you'll find it at: This should be the final update to the list of parts, as I won't be supplying any more kits after this batch. There may well be developments and improvements, in which case all builders will be kept in the loop. I'm picking up the cabinet kits on Friday and will be assembling all the crossovers and cable kits over the weekend. So builders should have their goodies for Christmas. PM's on the way with payment details later today. Incidentally, I notice that the latest plans have been downloaded 130 times. So there may be a few more of these cabs about than we think. 1 Quote Link to comment Share on other sites More sharing options...
