my switching 2A indeed PSU blew up. Opened her  up and the KA3842A SMPS controller was all black and obviously had gone kaput :/ Looked like some chinese no-name manufacturer so ordered a Fairchild-Semiconductor KA3842ACS along with 2 Panasonic FC 470uF 35V caps that do some final smoothing on the 24V end of the PSU to replace some crapola stock ones.

Gurusan, let us know how that repair goes, as I was comparing my Indeed 2A to the smaller Bravo 1A that came with my daughter's new V2 today. The Indeed was obviously quieter. If mine goes belly up, I want to try and fix it, too... just for the #%(( of it!

well it didn't go well. I replaced the DIP8 chip and it still didn't work so gave up and scoured ebay for a replacement PSU.

I found a Powersolve 2.5A 24V switching PSU. It's much larger and heavier than the stock indeed one. It sells for nearly 40GBP on Farnell but i got it for 6.50 shipped brand new on the bay

I measured the output and it puts out 24.5V under load....and the amp sounds wonderful.

Good on ya! What all have you done to your Indeed, mod wise?

Upgraded PSU cap to a 4700uF Nichicon KW, Mullard 6922, changed out a small filmcap by the psu for a wima....bypassed some other caps with a few film caps.
 
And changed the push-switch to a toggle switch.

I've got one of the new new G2s with a 6800uF power cap, IRF 510 MOS-FETs, and the 6922/12AU7 selector switch.  I'm liking it a lot so far.  It does much better with my low Z 'phones than my HD650s though.  Those sound much better from my Maverick D1.
 
I've tried a few different tubes in it so far.  I bought it (secondhand) with an Electro-Harmonix 6922EH.  It sounded pretty good, without roll offs on either end and a little bit of that tube magic.  The Sylvania JAN 6922 was much better to my ears.  It had a hair or two of roll off at the ends, but it's very smooth and has plenty of that tube magic.  The Sylvania Gold Brand 5814A is also quite excellent.  It has a very noticeable treble roll off, which makes it unsuitable for some headphones, but is very, very smooth.  The smoothest of the three mentioned.  I like the JAN 6922 best with my SE530s and the Gold Brand 5814A best with my SR80s and XB700s.  The Gold Brand and the SE530s are an amazingly smooth combination, but the combined treble roll off is to much for even my treble-shy tastes.
 
Now a quick question.  Does anyone know if the bypass cap mod (across the trim pots) compatible with the G2?

I have my trim pots bypassed with 100uF caps on my G2. I also have a Sylvania GB 5814 that is very nice with the G2.

Just getting ready to move back to the USA (Portland, OR), and snapped some pics of my indeed amp to sell. I started writing the FS thread and just couldn't finish it! I can't bear to sell this little beauty so it's coming with me!

Hi im thinking of getting one of these tube amps. I noticed indeed sells them with different tubes. May i know if they are all the same except for the tube that comes with them? And if so does this imply that it is compatible with any 6dj8, 12au7 tube?
 
Sorry quite new to tubes here.

 

[maverickronin]

There's a switch with two positions.  One for each type.

 

[jc22c]

yes there are beauty.
 
and how about T-2010 TUBE AMPS from MIT I have see it in this forum but it is disappear.
but it is say that can change tube in the same circuit no need change any component.
It seems very fun.and can change tube o change sound.
 
Is any can give a link web to see it. thanks.

Lazybum, the G2 is compatible with both the 6 and 12 series of valves. It really is great for rolling tubes. I'd recommend getting the 6n23p version as the 6n23p is a very good valve and will give you a good "baseline" for comparing other tubes. It's also cheaper...

 

[lazybum]

Ok ill be hunting for one. The price of these amps seem to be pretty high nowadays. From the previous posts it seems that it used to be possible to get those bravo or indeed amps for under $40 shipped. Now they're almost always above $55 shipped.

 

[Judge Buff]

That was true for the first generation of both Indeed and Bravo amps, but I got my Indeed V2 for <$15 plus shipping. I got my G2s for about $50 each shipped.

Judge Buff,
 
Was it you that said the Sylvania 5814 was a good tube to try?  It's a 12 series, right?
Waiting for my G2 6n23p version as we speak...
 
Cheers!
