New Tubes for my 6534

[Anonymous]

if you dont know what you're doing with your bias, google away. dont fuck with things you dont understand til you understand them bro.

imho, jj pre tubes = decent
jj power tubes = meh, and have a high failure rate

find a set of decent winged c or ruby tubes or even sovteks. you'll be good for years. use the ones that came in your amp for the backups.

Thanks for opinion
I know that Winged C are one of the best ones but I don't want to pay that big price. Not a big deal , I can afford them but why ? For that price I can get 2 quads of Rubies or TADs and I can still be pleased.
I know how to measure bias , it's not hard thing to understand. There are shitloads of tutorials how to measure bias in this peavey so you know...


What about this tube positions ? correct ?

in mine, i currently have:

V1- sylvania 6 hole wavy long plate
v2- shug 12ax7b
v3- sovtek 12ax7LPS
v4- jj short plate
v5- RFT

Yup, but this is for 5150 , and the location of V1 etc on 6505 plus/6534 is different ...

Can you verify if my previous thoughts were correct ? (about this locations , based on pics).
And what do you think about putting RFT 12AX7 in V1 ? I've got spare one.
And simple question : If the amp will be used at low volumes ( 1-3/10 ) the tube life will be longer(excluding things like bias etc ...) ?

dude, you're going to have to look up and research what the tube layout is for your amp.

at some point, as has been said, you gotta start doing some research on your own bro.

yes, an RFT will sound great in just about every position. only one way to tell though..put it in there and see!

Well , thanks for all , I guess I must try ...

This is right.

Ok , for poweramp I will get SED C EL34.

Now - preamp.
From what I found in the net , there are few tubes which will work well in Peaveys 6505 series.
- Tungsol 12AX7
- JJ ECC83S
- Shuguang 12AX7A/12AX7B
- Sovtek LPS (PI)

For PI I will get this LPS.
At this moment my amps has :
ECC83S JJ in V1,V5,V6
12AX7 RFT in V2
RUBY 12AX7AC5 HG in V3,V5
(all of the V slots I assigned according to the previous scheme which Dale B posted)

When I put RFT in V1 my amp lost a bit of bass but received cutting sound , it's hard to describe. But the sound was smooth and punchy. When I put again ECC83S JJ in V1 and move RFT to V2 slot - perfect sound, bigger bass , punchy mids , very silky highs.
I like the sound but it will be even better with more cutting appearance. Maybe I should leave JJ in V1 , RFT in V2 and put Tungsol or RUBY(Sino) in V5 ?
Is there any preamp tube which can give me lows of JJ ECC83 S(or maybe bit bigger lows) with gain and razorblade cutting of Tungsols ?
Maybe NOS tube ? But which ? It will be great if the price will be about the level of the RFT.

sylvania NOS vertically ribbed plate. 6 hole. the inside of the tubes look like this:

http://i.ebayimg.com/t/quad-sylvania-12 ... ~60_57.JPG

but they are commonly labled baldwin (in green), silvertone (orange or white), sylvania (red, orange and i've seen some white ones IIRC).

the OTHER sylvania ones with ladder type looking plates sound completely different, but, for certain types of sound are equally as good sounding, just different! these ones i listed above, are magical tubes. for my tastes, better than the holy grail mullards with certain markings that people love to tout for marshalls...

this is as far as i can lead you tonally....the rest, you gotta discover on your own. these mixed with some RFT's are sonic bliss in a 5150, and are what i have switched over to. i have currently in my 5150 that you hear on my vids:

v1 Sylvania
v2 RFT
v3 Sylvania
v4 shuguang
v5 sovtek LPS

Thanks !
I will search for them , they are really rare. I'm living currently in Europe so probably it will be hard to get them.

 

[Anonymous]

nah, they're all over ebay. all the time. just buy ones that are tested on a hickock, and a reputable tube seller and you'll get good ones.

 

[EnGl]

Ok , I bought bias probe , I measured all tubes and one of them was about:
37ma
34ma
33ma
32.8ma

I know that little difference is acceptable but this is good result ? Of course tubes are stock ...

 

[Anonymous]

it's fine. some people will say put the 37 and 32 on the outsides, and the 34/33 on the insides for the most evenly matched push/pull scenario

or swap em around.....put the 37/34 on the outside (or inside) and the 33/32 on the inside (or outside) for a larger swing...could yeild some interesting harmonics.

i know with my 5150, i can run an unmatched set of NOS power tubes that range for 20-35....and it seems richer harmonically to me than a matched set of other tubes.

I will do some experiment, we will se.

This bias value is not too high and can stay ? I like the tone very much , very ballsy warm and smooth. When I put also 12AX7LPS in PI , wow , what a difference - more low end and silky top end.

And of course that differences in mA between tubes are harmless for amp ?

 

[Anonymous]

differences are harmless.

did you get the sed =C= el34 tubes?

not sure on the bias. you'll have to find the tube specs and do the math. it's late, if i can i will dig around tomorrow and do a workup chart for you on cold/moderate/hot bias settings.

LPS is a great PI tube. you should also check out the mullard i mentioned too, its a 12at7. cleaner and a bit brighter, but tighter. boomier too. worth a try for 20$ if you have the spare change.

 

[EnGl]

OK I found my ideal tube for V1...
It's Ruby 12AX7AC5 HG , previously this tube was in different spot but when I moved to V1 ...
WOW ! Super Tight very punchy mids and smooth highs.

Only dealer of Ruby tubes is in the UK or Germany and well ... I will pay for shipping the same price as for the tube so it is stupid ...
But I found TAD 12AX7C , It's 9th gen Sino , probably the same tube as Ruby. Anyone tried them ? Opinions ?

And other question : JJ ECC83S can be in cathode follower stage ?

Not certain, but I think these are the same mfg different labels. I use the Ruby AC5s. I have tried the TAD. They sound close, but for whatever reason, I've always preferred the Rubys.

What is the difference between this tubes ?
This TAD has low noise ?

Longest re-tube in history. When will it end ?
