RE: Tweeter difference problem with 3.3Rs and more

Hi Satie,
Sorry for the delay in replying, - I typed out a long message earlier today but the stupidly unplugged my computer by mistake,- so had to retype it all! (Was using Wordpad not word!).
Anyway, - look like you've either been doing my all night Vampire special or you've been getting up at the crack of dawn to write your weekend messages!

I emailed Johnnie at Audio Origami. I asked him about Technics arms vs Rega arms, and he said that the Technics arm when upgraded is as good as any Rega. So that concurs with what you've said and what I've read. He can do Cardas 33ga ofc copper litz or Kondo silver fairy wire for the internal cable. And he can put the foam damping in the arm no problem. He said the external cable he does is a van damme SPOFC microphone cable. I think he solders it to the internal cable to the external cable. I asked him about having a continuous run of wire but he said that was not a good idea, - I guess as the internal wire is very thin?
Anyway,- will have to decide on copper or silver for the internal wire. Thanks for the info on the differences. The silver is much more pricey though like about 4 times, so I might just do the copper.

Yes you got it dead right with the Troika, - you will need some sort of pins to put the Toika tag end and the arm cables tag ends together. I used pins from a cartridge but it would be better to get something a bit longer, - it was very fiddly with small pins. Then yes you just tuck the wires away and tape up.

You are dead right about the LP12, - its not a good source for a wide range of material and systems. And the later upgrades lose the musicalty and charm so there is not much point if it sounds off with poor recordings, - you might as well get a more neutral turntable in the first place like the Technics and perhpas build some switchable charm into your system with the tube buffer idea (that's a very good idea)

Wow your speaker ideas sound grand, - a 21" woofer! Do you ever intend to get something based around these parts built, or build it yourself?!
Back to the Vintage Tannoys, - Well I suppose they must be pretty good as they are so popular, - they are very pricey on the used market (the Monitor Gold, red and silvers). Its one of those thing rich Japanese collectors want (along with Garrard 301 and Thorens TD124MKII turntables amongst others) , - so the prices keep rising. I bet the Tannoys are even dearer in the USA than here. I will look for a cheap pair, - never seen a cheap pair yet but I am sure a set will turn up someday. I could driver a small/medium sized pair with my Art Audio valve amp in triode mode without any problems.

I am sure I have not been hearing my Technics to its full potential as the suspension need adjusting, - and it so high on the left side it fouling the plinth, so effectively the suspension is disabled right now, - I need to get the right socket size to adjust the nuts on the springs, - then I am sure I'll be able to get it right and hear how its really supposed to sound.
DL304 should be here very soon, - maybe tomorrow or the day after. Can;t wait to hear one again.

Many thanks for the PLLXO info, - so do you reckon two 100K pots on each PLLXO in the positions you specify will give me enough adjusting range to get the levels matched for both when I want to use the Quad on the bass and NAD on the mid/treble AND vice versa? Like I say the Quad has about 7dB higher gain than the NAD. I could get 200K pots if hats a better option, - how much attenuation does a 100K pot give you vs 200K?
I've seen some bourne cermet pots for good prices
http://www.viewcom.force9.co.uk/data/trimpot1.htm
Would these Cermet pots be OK?, - I remember you saying the attenuation was limited with them though. Might a wirewound or Carbon track give me more range?. It might be nice to get a dual pot too, - which would obviously be a lot easier to adjust than separate for left and right on each section.
I am going to start the delam repair very soon, - so not tried the HP PLLXO yet, - hope do get all of the delam repair done this week though and get it out of the way. Bit of an annoying break with making progress with the crossover trial but its unavoidable I suppose.

Its annoying with the 2.7QRs, - it impossible to see if there is any delam as the the wires are at the front and not immediately visible, - youc an only see the magnets through the back of the sock, - the 3.3Rs are the other way around with the wires on the back and magnets on teh front, - its very easy to see dealm through the one layer of sock on the back. When I've done the 3.3Rs I will look at the 2.7s, - just taking the front covers off should hopefully be the answer,- I'll then be able to see through the front of the sock and if they need any work. I suppose its quite likely they might have some banana peel as well!

Wow your Lenco project sounds SERIOUS!, - you hand picked slate out of 400-500 tiles?!! That's dedication. Look forward to hearing about your progress, - have you any ideas what arm you'll have on this deck? Perhaps a 12" incher? Look forward to hearing how you get on, - guess some way off, - sounds like you've not started building this plinth yet in earnest!

All the best,
Colin
