My first boss never went on holiday, he was afraid that if he did when he returned his job would have disappeared... years later another one of my bosses went on holiday, he was in charge of the biggest department in the company, about 3000 people, when he returned his department had been disbanded and his last task was going on a tour to tell "his people" to find another job...

moral to the story, always holiday as if it was going to be your last one!

Thanks Peter for clearing this up.... 

Hi Boleary,

Where do you live?  I have a pair of Bert's earlier design speakers that you could have a listen to etc.  They are Oris 200 with AER MD1 driver sat on Onken bass cabinets with Vifa long-throw drivers.  I run them with an 8 watt tube amp and Berts Gainclone for the bass.

Ok so the procedure is to try 0.9Z-5 with RC1 first and if that doesn't work go to SP1, with SP1 roll back all the auto update except SP1, remember to turn HT on and I should be good... 

Chaps,

Just to get this right, I have to upgrade to the official SP1 before I can go to 0.9Z-5 and then switch HT back on?

Wasn't there some issue with the sound of the official SP1 or did that get sorted?

Sorry for not keeping up 

Brian

...its not a new paint colour is it 

Well that didn't work 

Went progressively up to 3 volts and still the dreaded hum so not dc then....

Thanks Chris, just listened to this on U-tube for the first time and have ordered a copy, thanks for the recommendation

I have DC on my mains supply     

This is causing by big new amp to buzz   

So I have just ordered the parts to build a DC blocker based on the Bryston amp schematic 

I'll let you know how I get on ......

I'm sure I am not alone in having that condition called the "upgrade itch" 

I think the current bout of the condition has developed since I received the NOS1.  I am fortunate that each episode of the "itch" comes around about every 3 years (I think some people have the itch more frequently than this?).

I can be happy as long as my overall system sounds "in balance" but when I introduced the NOS1 the balance went so the itch reappeared...

This time I've gone from high efficiency horn speakers to low efficiency electrostatics.  I was able to get a reconditioned pair of ESL63s from Quad and ,thanks to Mani who let me listen to his system, I went for the Sanders ESL amp.

The sounds was "Wow....ish" so as the 63s have been in circulation for close to ever (in hi-fi terms) I have read a lot about getting more out of them and the key area is the input caps.   So last night I bypassed the input resistor and electrolytic input cap and now I have "WOW!"

Balance restored and "upgrade itch" has been satisfied.....................or has it 


 
(just want to record a big thank you to Mani for spending his morning with me lifting the amp between systems and demoing his Quads, a great help in "treating my itch"  )

and I thought whilst I was doing this I would do something with Mona Lisa's smile 

Don't tell Bert, but I'm leaning in this direction also, I need to find a pair of ESL57s/63s


I have found the answer Mani

Perhaps a move to the "AMD side" would be worth a look:
 

Nice system Mani and the white one looks good, but did you consider painting everything BLUE? This would of course ensure total musical coherence.

Nice idea Mani, however, Japan is one of the most wealthy nations in the world so they are not short of cash what they don't now have is infrastructure or a supply network so how can we help with that? 
With the uncertainty surrounding the power stations and the timescales involved investors are moving there wealth from the Japanese stocks so perhaps the best "we" can do and perhaps the most efficient is to buy something made in Japan?
