Ordered the 05 long body (with RCA inputs and 1/4" + 3.5mm outputs) last month and should be expecting them in 2-3 weeks time. Can you also let me know where to get the Brimars or other tubes that match well with the Mullards? I bought the Mullards already.

Thanks GG.

Congratulations buddy.........

 

If you are ordering tubes get me some too!

Will do Gav. Just let me know how many sets you'll need, I'll probably get 1 to 2 extra sets just in case!

post #2464 of 3704

I've only read the first 130 or so pages on this thread. 

GG: I ordered 4 Mullards. The Brinmars seem too be gone, although maybe I just can't read German. Please keep the suggestions coming. I'm probably not as critical as most of you, but I would certainly throw down for what is considered the 'best' tubes, or ones that help extend the bass, as neither this amp nor the UERM are overly generous in the fundamental frequencies. 

I should add that I also speak French pretty well if anyone needs clarification on those sites.

Ian: I love Wilson speakers. I would love to hear your home system some day. Are you a vinyl fan? I use a Sound Devices 702T (my old 'portable' player) to rip vinyl off of a Linn LP12. 

I can't wait 'til January.

Cheers,

Sam

Holeout, congratulations, very much looking forward to hearing yours and Sam's impressions once you get your amps!

Sam, I think of all the tubes the Mullards in the 3S4 stage will increase the bass, in fact thinking on it if you also went for them in the DF91 stage you would get a bit more. Don't be afraid if you go that route that it may sound a little dark at first, the Mullards really open up nicely with hours on them.

Other than that listening between the red letter Brimars and the Mazda?Cifte's there is very little difference between the two in everyday usage.

This is the seller I got my Mazda's from, you might want to ask him if he has any more but if not the Cifte's he has for sale are identical in sound and lovely quiet tubes.. Highly recommend this seller, great to deal with as was the British seller of the Mullards I showed you. The German sellers I find tend to be very expensive, it is worth searching eBay as often as possible I find.

An to clarify, the benchmark system I mentioned is not mine but a close friends. I have not had a home system for a number of years as I live a pretty transient life! I am planning on moving back to Europe as I mentioned and when I do a home system will be top of my priorities, it will be wonderful to get back into vinyl. I have some stored in the UK.

I love the Linn, had one with an Aro arm in my old Naim system back in the eighties. Still not have decided on a TT yet, I do like Brinkmann though.

Thanks for the 1T4 link. Please keep them coming! Black and orange for me as well with all the goodies.

Thats great holeout! I will be sure to post some links as I browse eBay.

There is a really great seller in Canada as well. His prices are higher than eBay but he sells excellent quality valves.

He tends to not show the exact stock so I would email him and ask him what he has in stock for the tubes we use.

I was very tempted to order both. Clarity and full bass is a tough choice. I'm going to start with the 05 and see how it goes.

I'm along the same lines. Thinking of get a 06 to pair with HD800 but seems the impedance is not well matched, anybody tried this pairing?

Thanks for the pointers, will definitely check it out.

my tur06 can only drive my beyer 880 pro 250 at not so loud volume.. It think it is best to drive up to 200 ohm headphones..

I was just grazing around the internet and found some Japanese pages about Analogue Squared Paper.  I thought I`d post some pics here of older amps and other interesting stuff this guy has done.

just received an email from shikada san that he has sent out my custom case and the other parts i ordered (secound battery, secoundbias battery pack, some cable for the internal power supply board, some original tu-05 style switches) for my mod.

 

but best of all i now know that he will sell me a second internal power supply board and i am very happy as this is the key part for my double mono mod completely separating left and right channel.

 

at the moment i am thinking of the overkill power supply solution without any active parts ( the internal power supply is a miniature switching power supply so producing some rf frqeuencies and ripple / noise).

 

i did not measure the voltages used up to now, but using the specs of df91 and dl92 + filament power /  heating, one need

 

- 1.4 volt for heating

- some 3.x volt for the ledś

- minus 7.5 volt bias

- plus 90 volt anode voltage

 

which means (90+10+some additional) / 3.7 =about  30 Lithium Ion Cells and 22 Li-Ion mini charger boards + 1 NiMH- battery for filament power / heating + charger board.
