Guys,
Thought you'd like to know that the presoldered THS4032 board and decoupling cap combo is back on ebay. If you want to try the THS4032 this is a drop in upgrade on the 7520 - no soldering required.
It sold out in a couple of hours last time (6 units), but this time they've put 20 units on sale. I've already had another one myself.
Heres a link --> http://cgi.ebay.co.uk/THS4032CD-Dual...1%7C240%3A1318
Two more gone, but then I'm done fiddling around for awhile! If they're that much better than the 4562s I'll be a very happy camper.

Stupid idea? :mental:
I have a feeling there's a different type of socket adaptor used on Trailers which will allow the lid to shut.
On my unit you have the green pcb then some brass coloured feet and then the black plastic of the adaptor - on the photo's of Trailers it looks as though those brass feet/spacers aren't there (Could be the photo of course)
Yeah a chock at the front and back would work or to be really crude pop a dent in the underside of the lid where the cap is to allow the lid to close with th ee cap underneath (Not exactly pretty though;))
I'm going to have to think of something though as they sound great so aren't going anywhere!
Eeeeeurgh! No one would dent their case would they? Maybe put a hole through-like the Modwright Transporter where the valves stick through.
Here's an (incredibly aweful) photo to kind of show what I mean by the feet/socket etc.

Emailed the guys at Tirna about this very issue, heres the reply:
Hi,
If there is an IC holder socket that the previous chip was slotted into then yes, you can just put the new chip straight into as it has turned (round) pins suitable for insertion anto an IC holder. Otherwise you will have to solder it into place. I can confirm that the height of the chip from the start of the plastic part of the pins to the top of the capacitor is 10.5mm. You will need 10.5mm of clearance when the chip is mounted into an IC holder, and it will be taller than 10.5mm, when the chip is not slotted into an IC holder. As I have never seen a Beresford DAC 'in the flesh', I cannot give any more accurate a description than this.

Is it possible to slide the black plastic spacers off the pins and snip the pins shorter? I don't see why you need the spacers if you're going to continue using the IC socket.
I would have thought that Alan would have done the sensible thing and buy a TC-7520 to make sure his modification would work and fit properly in a TC-7520 before he lets TC-7520 owners find out the case won't close. I am most disappointed that he is cashing in on the craze without giving the right sort of support for his mod.Quote:
