Can't tell you as I got mine for £20 and never listened to it before modding

From experience and talking as a "serial modder" they can sound better or just different. I just love tinkering and I think that because you have done it yourself, and the patient has survived (hopefully) it DOES sound Soooooo much better

...or worse, don't forget worse! They can sound better, worse or just different. I think that covers everything. Oh yeah, or silent.

I've been through all of the above. Mine sounded like it was trying to take off at one point. Now it sounds much better than stock to me. I guess the key word in the original question was 'after', i.e. how does it sound when you have finished modding? If you are committed and you draw on the knowledge in this forum then you are most likely to keep going until it sounds better. The bigger question is will there ever be an 'after'?

Yes, good points... I hadn't considered the alternatives of 'worse' and 'silent'.

I see what you mean... when you start modding it can become a continuous process. Will we ever finish?
I'm looking forward to it!

Good points. They can sound worse before eventually sounding better again if you commit to making it sound right to your own ears.

Hey guys, I've started ordering DOS parts, working pretty much off Brent's list. I ordered some matched pairs of 2SK170BL, but now realize that they probably should've been 2SK170GR. Is that right? I read that the difference is something to do with current range.

I'm getting 1% Cornell Dubilier silver micas for the signal caps, although I was tempted with the SGM 0.3% mica-in-oil ones. I remember some of you were looking at the Amtrans caps too.

I'm not sure if I really need to fit DC blocking caps, as I have the 3.3uF Silver Oils after my amp's input selector switch.

Any more good DOS experiments lately? Any more component ideas for a no-holds-barred DOS build? :-)

Most important for the DOS are decent regs (thats not 317 type!!!)

Seriously, I've just put 9 of my regs in a 67 for a pal that had the usual cap treatment along with a clock, clock psu and output stage upgrade. It was really quite something.

If you want really hi-end, you need decent regs ;-)

Yep, understood Ian, I'll most likely get some SPowers. I'm mulling the external PSU too. I hope someone can shed some light on those 2SK170s for me - i.e. are all blues OK or do I need greens? Is anyone else building a DOS right now? It's expensive sourcing small numbers of parts bit by bit.

Do you build your regs yourself, Ian?

Yep, after the 12th or 13th SPower and realising their massive (understatement) benifits over anything the same size, I set about building my own similar regs. There are other regs which are good like the 317 tracking pre reg but its more difficult to build them small.

Not sure about the 170's. I think the gain may be different on different type (something a poss remember Lee saying to me at some point) so as long as they are all the same type you should be OK. Use Brents mod on the CCS and use RC55Y resistors. Thats what I use and I think Brent the same. If you were feeling really posh, you could use Z-Foil resistors in the filter!!!! I use silvered mica caps in the filter, I think Ray preferers styrene. Final part of the puzzle is the output cap. I use Mundorf Supreme 4.7uF. You really get what you pay for here but its a personal choice. I think Brent now runs Supreme silver/gold/oil......I'm too scared to look up the price of those!!!!
