Well I completed my build today fired it up for the first time and nothing Not even the heaters in the tube light up. I try to adjust the 1k pots but it makes no difference to the voltage, its always 24v exactly the same as the main input voltage.   I think that the K117's may be damaged.  

Well I will just see if I like it only being 1000uf. I've almost finished  just waiting for the 1k pots and tube socket its very frustrating as they were ordered a week ago!!   I'm using Elna silmic II, K40Y-9 capacitors with IR510 mosfet and a Mullard ECC82 should be good.

Has anyone tried using an 1000uf capacitor for C103 like on the schematic?  Reading through the forum people have commented that 1000uf its not big enough.   I ask has I have a 1000uf black gate which I won off ebay dead cheap and would like to use it, I know that it would make the ...

You think this would do the job?   http://cgi.ebay.co.uk/FC1237-Headphone-amplifier-protection-kit-DIY-C59-/120656345258?pt=LH_DefaultDomain_0&hash=item1c17adb8aa   This would give the time for the amplifier to power up before the relays kick in hence no pop sound. Well this is what...

I'm very curious to what the 680uf bias caps actually do. I have a V2 bravo and just bypassed the 1uf Rubycons with 2.2uf Wima ones to hear what different it would make, it changed the bass some what.    

Hey guys   Would like to tell you the weird problems my bravo amp has developed. It has left off for many months until I got some new headphones. I plugged it back in and all seemed normal. Until I listened to some music it sounded like crap, the sound card in my PC sounded much better then...

I will keep then for 3 weeks and if I'm still not happy with them I will ebay them.  I don't think I will lose out too much as they are popular headphones.   Its funny that the headphones I prefer to these cost around £35, I think my ears must be messed up  ...

How long would a pair of SR80i's take to burn in?   I got my hands on some and I'm quite disappointed over my other headphones. Should I just leave them playing music all day?

Here is the value in question, Sorry the pictures are not that great but you get the idea.  

To be honest I'm a complete newbie when it comes to values. My Millard cost £18 with postage. I will post a picture of it here so somebody more experience can identify it

The Mullard value I got for the bravo sounds fantastic!! Its like a breath a fresh air, very nice!!   I've just ordered myself some Grado SR80I headphones, I'am also using an Asus Xonar D2 as a source.   So I should be in for a real treat!!

Thank you for your input, appreciated.

I'm new to tube amps,   Got myself a bravo v2 off ebay and wanting to replace the stock tube. Looking on this thread I found that mullards where a good choice. Ive got this tube off ebay.  ...
