Wow, the years go by. Nice arteom…. And hpamdr who’s post from 2015 I just saw 😬, the original breadboard CTH used a pencil tube. I do occasionally pull out a DIY CTH but usually use an Amb γ2 DAC -> Liquid Spark and have for years. Sometimes with a Loki Mini+ in the mix depending. Happy...

Good seller. Nice, fast and easy transaction. Saga S came in good shape and works well. Would buy from again for sure. Thanks!

PM’d. Also curious why it’s rated good; what do you see as any issues. I do see the finish looks odd in the photo; maybe a closer one would be clearer.

Thanks for letting me know. Updated a few of the links in my sig. I've built and heard a lot of headphone amps. Part of the reason I stopped building; Too much audio gear & not enough space (or ears:) Though I do plan to someday build out a Bruce Heran 6DJ8 Headwatt I bought the parts for...

I still watch this thread. Time flies. Noticed your WTB post, hopefully you'll get a hit. BTW I own both a nice DIY CTH and a Massdrop CTH and rotate both in from time to time. DIY CTH gets play because of its greater tube rolling (voicing) options; I've lots to choose from and find that...

IG is input ground. You can tag IG wire along with any nearby component's connection to ground (PCB top layer). E.g. R1L resistor's lead/pad right next to IG pad, or nearby R1R lead. You can see their pad connections to PCB top-plane/ground and use ohmmeter to confirm. Note also that IG=SG.

Don't do much of this any longer but John pinged me & I offered this: "Times like this call for the Wayback Machine ( http://web.archive.org ). Typed in cavalliaudio.com and the Jan 14, 2011 snapshot (press 18:13:09) looks like one of the "best" to me. Quick look indicates it has all the *text*...

The repaired indicated in the other forum that he did suggest raising the resistor values.   So it appears it may have went sort of like this:   BTW should correct my statement:  All β22s that have passed my way have 1R R34s & R35s.  Did this even to a 4-channel/balanced build I sold because...

Posted the below at the other forums you posted this plea to.   Again I'm way too backlogged with work to take this on, but between you wanting it re-cased & it now needing work IMO may be best to sell it off.   This is always disappointing to see because its so avoidable.  Besides lowering...

Thanks for the post rds, good to hear your CTH is still serving you well.  Though I listen mostly to speakers these days, I do rotate a CTH in every now & then when using cans & still enjoy it.

Thank you for the detailed info and impressions and its nice that it was worth the effort of doing. A picture might be nice too but maybe its not too pretty:) Sometimes that keeps me from posting them. I guess if one was so motivated they could make a really compact CTH going to SMD and...

Had to go back in my archives for this one:)   First off I suppose your CTH has a regular 9-pin socket installed....  So maybe use a "9 PIN TUBE SOCKET SAVER FOR 12AX7" or "9 pin Machine made tube socket 12AX7" (w/o center pin) from fleabay to wire the pencil tube into so it can be inserted in...

Sorry I did not mean to offend, sounds good - an O2 build is a good warm-up:)   Good to confirm any questionable sub parts as you are doing.  But concentrate on Description field value in CTH XLS BoM when an exact part # is not available from your source(s).  E.g. in the Digikey BC550CGOS-ND...

No, use the base part & classes specified (e.g. BC550 - class C).  E.g. in the case you ask about either BC550CTA (ammo/tape) or BC550CBU (bulk/loose).   Curious, how many builds do you have under your belt?   The CTH is an intermediate level build, *lots* of parts in a tiny space, and...

R4H & R5H are resistors you'd only purchase & use if you wanted to support more than (popular) 12.6v & 6.3v heated tubes.  Most builders use a SPDT toggle 12.6v/6.3v (thus not needing R4H & R5H).  See also: http://cavalliaudio.com/diy/cth/main.php?page=schematics/psschematic
