Yes, of course! It's a board for bodgers, and there's nothing special about any of the partsI ordered just the XO and PCBS seeing as though I already had most of the bits. Will a BC547B and any 5mm green Led be suitable?
So long as the Tent XO gets 4.8 to 5.2v you're fine. Red leds seem to give 1.65-18v, greens about 1.95 and blue /violet vary 2.8-3.6ish, so if you wanted you could twiddle the output voltage with adjustment of R6(see manual). Differences between a leds of the same colour are much smaller than the amount it will drift due to temperature /warm-up.
The slightly lower current gain of the 547B (as against C) is insignificant - it will just drop a few more 1/100ths of a volt across the cap multiplier.
