I would dare say that because of the different bottle they sound different from the tall base ones.

It's been long since I used them so I am only guessing.

I think the glass on most coin bass tubes is actually the same height, it just looks taller because more of it is exposed to see.  I have seen exceptions though, the ones with the very long wire structure in the base which makes the plates look like they are standing on tall stilts.  Since tubes were on their way out by then it must've been done to make them cheaper to manufacture.

Mine seem exactly the same height from bottom to top and the actual assembly inside the tube is as well. It seems like they just didn't pull up the plastic sleeve to meet the outer diameter of the tube glass. I've tried them out both now for a bit and I can't hear a difference myself, the rest of the setup being identical. One drawback would be because there is little to get a hold off on the coinbase besides the glass, I guess I should be extra careful pulling them...

Thanks!!!

 

It's an SP MPX3 SLAM (toaster style).  At the moment I'm using the HFI-2200s.  The 6SN7s are rocking.  I had been using 5687s (with adapters) & 7N7s (with adapters) which sound great but it's good to come back to a little 6SN7 love...

I have a SP PPX3-6SN7 with a pair of NU 6F8G round plate output tubes and different drivers.

 

I have used a few 7N7's but did not like them as much as the 6SN7.

 

Tip: I f you have any noisy 6SN7s put them in the output position. The operating voltages are different from the driver position so you may never have any noise issues again.

Thanks ros...

 

The 6F8G is the only adapter I have not tried.  Thanks for the tip...I recently started rolling the 6GU7 (with 6CG7 adapter) and have to say it is a great sounding tube and very economical.  I have a PPX3 SLAM as well and only use the 6SN7 as driver, so far no probs.  You don't like the 7N7s?  I got hooked with the 7N7s & 7AF7s as well and now the prices have been jacked up considerable on the 7AF7s than a few years ago.

All the 7N7 and 7AF7 were made by Sylvania (Loctal Types) so there is not a huge variety.

The 7AF7 in particular have the same construction, no variety there.

I have tried the 6SL7, 6CG7, 12AV7, 7N7/7AF7, 6F8G, ECC32, ECC33, ECC34, ECC35, ECC40 and 2C51 family of tubes with my SP's as 6SN7 substitutes.

 

My favorites are the ECC family, some 6SL7's, 6F8G and 2C51's so far.

Warning: the ECC family (except the ECC35 and ECC40) may/are not suitable for you amp.

 

 

I am an Ultrasones person.

lol...I have been around for a little while and I knew you were an SP and Ultrasone man.  I follow your threads...I also own an Extreme (love living on the edge...lol)...As far as Ultrasones, look at my profile, I'm a fan as well.  The 396A, 2C51, 5670 tube is one of my favorites as well.  Sylvania Gold 5670s and Ultrasone are a beautiful match....

SLAM basically means the 5687s as power tubes (w/ or without adapters).  What is the model that you have?

Well HF, thanks for the kind comments it's nice to know I am not alone in this crazy hobby.

We have met before in the Ultrasone thread, If I  remember well.

 

Congratulations dear Kiertijai, I am sure you'll love this little amp.

Best have it checked for safety first to be sure all is well.

I use the Grado SR325is permanently with one of my Extremes and couldn't be happier.
