So, lets re-design it for pocket sized fun :)
Sounds like all is well w/your CTH now.
Re: re-design - Y'all may have noticed things are a bit quieter around here. My guess is it may be a combo of there being plenty of designs to choose from & maybe efforts happening in the dark / elsewhere, which IMO is fine. Personally, I've enough gear for 3 or 4 audiophiles:)
But I'll probably not be able to resist the smell of solder for long. E.g. it dawned on me I've never made an exceedingly simple headamp (other than may my 1st - the SOHA), like one w/a dozen or so parts per channel total.
So kicking around the idea of trying something involving an actively loaded grounded cathode input stage (from a schematic Alex passed to me way back), an IRF510, this SMPS:
some other bits & a 12VDC wallwart and see what happens (perhaps not much:) Someday anyway.
^^^^ Yeah, don't both w/that nixie SMPS for audio. It's switching freq seems to be in the high end of audio range. Something different might work tho.
