And pair them with (what I think are) Mullards on the bottom of your 3s4 stack. My th900's truly shine with this combo!

 

Great. Thanks a lot woodcans, Much appreciated. :beerchug:

 

@xplosive : we'll keep in touch mate.

Wowzers Boringer, you have some esoteric tubes there!

The Rogers are a Canadian company and from what I can gather their tubes are generally re-brands of other makes, especially Dutch made philips (the same company that make the famous Amperex bugle boys's)

Teonex were not a maker of tubes but a marketer so even though they may say made in England they could be from anywhere. I have seen though that a great many were in fact Mullards.

Those "Stamp" Philips are the most interesting. In shape they remind me very much of my Marconi's. Could you take a picture of the lettering for us close up. I might be able to find a factory code and let you know where they were made.

As WC said though. get yourself a pair of the philips DF96's he mentioned. As I said previously they are identical sounding to the Stuttgart Lorenz DF91's I have and are wonderful tubes, pair them with the Mullards (my Philips DL92's are Mullard made so sound the same as Mullards) and you have a beautiful combination of air, clarity and bottom end!

In the meantime I say try the Tungsram 1T4T/Mullard combo, that comes within a hairs breadth of the Lorenz/Philips DF96/Mullard/PhilipsDL92 combo in my experience.

Give them at least ten hours, preferably 20 and still expect some settling through 40 hours before they really come on song and quieten down.

So funny as I always think of Philips as a Dutch company and yet the tubes are German and English!

So ... how do you like this " ALL_Philips" Combo ? 

post #2705 of 3496
Today a lot of the ' final' parts arrived:



This includes the resistors, capacitors for the amp, all the neutrik jacks and connectors, a neutrik usb port, .., capacitors and resistors for the loudspeakers, switches, and more.

Really really excellent. It is the same as having the Philips DF96/Mullard DL92 combo as my Philips were made in the Mullard factory in the UK.

The difference (very slight) between this combo and the Marconi/Phillips combo is that the Philips/Philips combo has a touch more weight to the presentation. I can happily live with both presentations to be honest as I like both styles.

I do think that if you listen to a lot of full scale orchestra then the Philips/Philips combo is the one to go for as it gives the edge on sense of scale I feel. So not better or worse, just different ways of conveying and I am very happy with both! biggrin.gif

a short story about good luck: a company in the same building designing electronic components for the industry made an inventory and trashed all the older electronic components and parts.

 

i got a lot of cables (bnc / koax and banana) for my power supplies and oszilliskope / signal generators, a lot of screws and nuts, aluminium plates and pieces to mount for example the switches and potentiometer, 4 housings, a complete 19" rack housing, transformers, potentiometer, a lot of switches, knobs, wires, wires, wires, and a lot of single parts. has saved me at least 500 Euros and now i have all parts to make my own housing for my desktop version!

is this working with Tu06?

post #2709 of 3496

the df96 should work as they work without any problem as df91 in the tu-05 (in fact the df96 seems to be a df91 with half the power needed for the filament / heater.) . the 3s4 is NOT working as it is a dl92 only for the tu-05.

post #2710 of 3496

today also four of this small crystal radio output transformers arrived:

 

 

they are really small, have a high inductance ferrite core and an amazingly wide impedance range (32ohm to 200 kohm):
Processed By eBay with ImageMagick, z1.1.0. ||B2

i will definetely try them together with the subminiature tubes (df61, dl620) for my mini tu-05 mod and also will test them maybe just for fun with the tu-05. furthermore seeing the specs i think they can be used as 13 step  input attenuator, sadly not balanced as they have only one combined coil.

Do we have some kind of tube list for tu06?

 

Thankls

Basically the TU-06 uses the voltage gain stage tubes from the TU-05 so any of these will work without modification or pin cutting (Ask GG about that as he is the master of all that as well as our head mad scientist and technical guru!)

1U4 (DF904)
1T4 (DF91)
1AJ4 (DF96)
1T4T

is this has to be match pair or can mix?

post #2714 of 3496

no matched pair needed and the list of ianmedium is correct.

Though you could mix and match I would go for at least using the same type together (1T4 with 1T4 and so on)

I personally feel there are sonic gains to be had with pairs of the same make as well and if you can get pairs matched with each other on date even better

For instance just a quick look on ebay finds this seller selling a matched pair of mil-spec RCA's from 1952 (By the way, this brand are excellent sounding)
