I'm a high roller, I buy doubles of the boards

he was selling his queue spot at cost (plus fees and exchange rate) so I took over his place in line for the price of the preorder I was too curious about the grounded grid part of things so I went with it on impulse

That would be the one Justin is burning in, I purchased Amos's spot in line. I wasn't aware pabbi tried to tackle a BH, I bought some parts off him earlier this year when he mentioned he wanted out of DIY for the time being.

Should be thousands of hours like any other NOS EL34, but someone else can chime in as a more accurate tube lifetime in a BHSE. I'll let you know when I receive my own BHSE (Currawong's unit), but with the Megatron I've been using RFTs ~8-10 hours a day at the office for 6 months now, no signs of faltering. I think national 6ca7 and possibly telefunken EL34s are equivalent

NOS RFT tubes are another alternative, certainly not XF2 tier but something to consider...order of magnitude cheaper as well

so the spritzer-preferred 007 can be obtained in all black? maybe I need to hock my mk1s... did you do any other mods outside of port plugging (to the mk1s)? what mods are you exploring on the 009s?

I think that seller on diyaudio stopped selling 3381s in moderate quantites because the T2 ruined his christmas

stepped attenuators? say it ain't so

so basically you saved head-case thousands of dollars, truly a boss among bosses

I'd be down for a full kit, I was definitely toying with the idea of finding parts for the original version

I thought you rid yourself of a pair 009's some time ago? Any particular reason for revisiting them? The exchange rate has been looking pretty inviting for quite a while...

how's the hum (if any) with torodiy? that power supply looks insane

for those of us too poverty for angle brackets, will there be issues with the additional parasitics if we mount devices near the sink and use wires to get to the main amplifier board?

Are the 2u heatsinks enough for these devices? What's the size compared to the original DIYT2 sinks?

No worries, easy to gloss over things when porting files around I also don't see any 2sk216 in the battery schematic, but they're on the silkscreen

10m90s on the board bottom has 120 and 100, top has 300 and 100, schematic has 300 and 200?

four boards might give a little more flexibility in casing, you can stack the output stage over the front end Might be cheaper to fab four smaller boards as well

is 1156 a direct drop in for 1486?

I haven't heard the O2, is it actually a good amplifier? I can't imagine nwavguy knowing enough about class B amplification to make it sound good. I think the M3 is supposed to be similar to the BCL, but that was just a glance...if I owned dynamic headphones I'd probably get some boards made for the new dynalo. Personal preference

yeah I'm just being a dipshit, but why do people keep defaulting to the b22 anyway? it seems pretty expensive for the end result. the more I hear it with the hd800 the less impressed I am

2 is also prime ari don't spread misinformation

are you reusing the original diyt2 supply?

From what I've been reading it seems like the notion of an ES circlotron is overkill incarnate - rail to rail floating supplies for each half of the output Would the design see tangible gains from paralleling devices/tubes?

once the kg carbontron is brought into the mix there might be too many endgame options feels bad man

curious as to how it sounds over the mergertron
