I wonder how long those CDPs have been sat idle? Those BG caps will take 100s of hours to break back in and show what they're capable of.

My experience is aligned with the above. YMMV
I would not fit anything Nichicon - very averageThx for cap recommendations all!
Are the SMT caps on the bottom of the boards (and that dale resistor) OEM? I'm surprised that a diyer who's into Reiki crystals and Exotic ££ caps isn't also into tantalum / shinkoh resistors
Utterly- this.
Some years ago, discussion elsewhere proved the utter-idiocy (... it did not take long ...) of using a valve in a clock reference circuit. The 1/f, let alone higher orders, is ..utterly, despairingly, wild / F'idiotic.
Bin that, restore local order: enjoy.
So they just copied what’s inside the regulator and stuck a tiny PCB on a regular power transistor? Really or there’s more to it?Just googled a bit - I think they are Sparkos Labs discrete regulators, fitted as default to a lot of Hypex builds it seems

I’ve used 78/79XX regs since about 1980 I think and have never had to complain about them.
I disagree! A valve oscillator can be one of the best available, but I certainly wouldn't have done it anything like the unit here which has been made to appeal to "steam punk" sensibilities. Linearity, lack of signal modulated internal capacitance's, lack or Early effect, high impedance's at RF and ability to work at high voltages and power levels (especially with the larger old type crystals which can take some power through them) can, when done optimally, result in a cleaner output spectrum and lower noise sidebands etc than most SS oscillators. Type of oscillator also makes a big difference and IIRC from RF days the Franklin and especially the Butler oscillator are well suited
Well there you go. What about an @Arkless Electronics aftermarket tube clock?
Oof, I was asking for that!
Now come on Jez, you said above that valves can make better oscillators the solid state...
