I recently experienced using a Bugera RAT amp for the first time, which is a 0.1,1or 5watt valve amp with various modifications as link below.

http://www.ratvalveamps.com/bugera-v5-combo

 

I was blown away by the sound (not by the 350v inside!)

I now know 3 people who were also impressed they bought one too.

(mind you it's not cheap!)

 

As the valves can be changed inside them to vary the sound, there is now a debate to what is the best sound available and what valve is best.

 

The information keeps pointing back to NOS Mullards, has anyone any experience in valve speak?

 

The rectifier valve is being changed soon to a Mullard EZ80

and have a vintage Mazda Ecc 83 to try

 

Here is a link I found:http://www.watfordvalves.com/cgi-bin/documents/testreport_2.pdf

 

Any info is welcome on the topic of best valves and circuits etc.

as this facinates me how it all works.

 

 Thanks for your help...

 he must have been off in the neighbors garbage hord looking for inspiration or something ??? 

and yes I found something hang on a tick...

A leather brief case sound fine!

I'd venture to guess that most anything would be a big improvement over the inexpensive stock Chinese tubes that are supplied with most relatively inexpensive tube amps. I say this as a audio/music enthusiast who has been running predominately tube electronics for many years.You can drop a ton of money on NOS Mullard, Amperex or Telefunken's but don't rule out the GE's, RCA's and many others out there that can provide really nice results also. Rolling boutique brands from the past can be outstanding and an eye opening experience from a audio playback standpoint but unsure how that plays out where guitar amplifiers are concerned.

That said, I dumped the stock chinese junk and  retubed my Fender Excelsior with GE 12AX7's and a pair of nice testing black glass 6V6's pulls and it changed the tone (for the significant better) of the stock amp completely. So much so, that I have put the planned driver upgrade for the amp on the back burner.

See if you can find yourself a old tube organ at you local thrift store or at a garage sale. You have to know what you are buying but you can usually find them cheap and many times contain enough 12AU7's and AX7's etc. to last you 2 lifetimes. They many times test very well. Most of these old tube organs for the home really weren't used that much and you might get up to 30 or more usefull preamp /driver tubes that test dang near like new.  

Thanks Ron, I nearly bought a wind organ a few years ago....looked kinda cool but too noisey for recording

I have to say the nos valves sound kind a cool...forget tranny amps this takes your sound to a new level..

Heck yeah, I like some solid state gear but for me, tube based stuff usually sounds the best. I have a couple amps around that run the same tube compliment (12AX7, 6BQ5) as your Bugera. They are neat amps and their are a ton of tube options out there for both tubes. The thing that your Bugera has that these do not is Tone and Reverb. The RAT looks to be much more versatile because of that and I bet it sounds cool as hell.

Let me know what NOS you picked up. I may be able to dig into my stash and find you some Amperex, Telefunken or something to try along with what you have there
