post #3496 of 4214

I'm looking for a... 9 pin base to 6sn7 {on top } adapter.

 

This will used on the Crack Amp  w/speedball..

Is this doable,& is it safe?

 

Anyone  know where I can get this,in the USA,or have one built?

 

Thanks

Mike

Are you thinking about a 12AU7 to 6SN7 adapter?

 

Like the one shown in this auction?

Yup,thats exactly what I am looking for..

Is it safe to use this kind of setup??..don't want to blow up my Crack amp..

 

Jesus,don't know why I couldn't find it on e-bay?

You wouldn't happen to know of a seller in the USA,would you?

 

Many thanks Rosgr,

Mike

It is safe.  I use the adapter in my Crack.  Doc B from Bottlehead says it is safe too.

Be sure and get the 6.3V version, not the 12V version.  They look nearly the same.  The 6.3V version is shown in the link above.

Just search for 6sn7 adaptor on ebay and you get alot of results returned. That said I have at least one of each of all those adaptors available and the 6sn7 upgrade using an adaptor is the 6F8G.

post #3501 of 4214

Do you mean,its the same as using a 6F8G tube..???? ..not sure I follow you?

 

Do you have any issues with the adapters,such as ...noise?

 

Tnx

Mike

No noise issues except I did get a bit of hum from a few of my Tele 12AU7 using one of the adaptors, turned out to the adaptor have a fault. 6SN7 adaptor that takes 6F8G tube is an upgrade over the other tube adaptors. But 6F8G tubes don't really come cheap and not much of a variety available.

After I got the crack--I went on a 6sn7 tube spree..dont think I payed more than $30.00 for any of them..bought maybe 5/6 tubes?

 

So,now I will have a chance to hear them with the TS 5998's

 

Tnx for the info Def

another tube roller in the making. Your wallet will soon feel the heat. But it's worth it nonetheless. Happy tube rolling Mike.

It's already started...I went threw this when I had the Lyr.
yesterday,I bought a pair of WE 421a. & a GEC straight brown base.

I,ve been hiding from my wife ,ever since then !!!!!!!!!!
post #3506 of 4214

GEC, nice :) Pick of the crop.

post #3507 of 4214

Damn expensive too.

Here they are:....OUCH,

And,,ouch again,

 

http://www.ebay.com/itm/221218283945?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

 

Honestly,I have a feeling,that the WE's will sound almost identical to my TS 5998's..which, with the 12au7 Siemens,silver plates,,are unbelievable.

 

A few guys have commented,that because I'm using the HD800's & crack amp,,that MIGHT NOT  be the case,because these cans are so resolving.

Atleast I hope so.

 

Any opinions/comments would be appreciated,as,it might assist in easying the pain,while my wife removes....ahumm....certain parts of my anatomy.

A 1940's to 50's CBS 5814 drop in to replace your current Siemens should take the sound to a newer level with that 5998. But again if you get a GEC brown base in there you should even get a better layering of depth added to your music as GEC tubes are good at but I haven't heard the 6SN7 variant yet but Rob (Skylab) reckons it's the best out of the family.

post #3510 of 4214

We have gone back and forth quite a bit in the 6AS7 thread about the WE421A tubes.  The loose consensus is that they are not *quite* identical to the 5998 spec-wise but probably sound so close that there is no point in differentiating.  I personally would not pay the premium they go for over the 5998 which itself is crazy expensive now.  The WE's certainly are pretty though, they seem to always be bottom getters where as most (but not all) of the 5998 are top getter.  Rob has some of every variant I believe, but I think bottom getter tubes are always a little sexier than top getter ones.
