I buy mine from Sparkfun and from Futurlec. Since you are in the same part of the world as Futurlec (Thailand I believe), you might get quick shipping.
- red 6 pin --- very handy for those sweet sweet JFETs that are only sold in SMD
- green product selector -- click the individual headings to see pricing @ quantity
I've had success using these Texas instruments adapt to PCBs.

If you're looking for something cheap, I can send you some if you pay for the shipping to Australia (from UK)?
PM me if you're interested.

2 x Single to Dual Adapter Board
Does anyone know if there might be an adaptor board that will accept 2 x single channel opamps that can then plug into a dual opamp DIP 8 socket?
If not I am thinking this would be a great upgrade option for this board. I could be motivated to make one if people are interested.
I would like to try OPA2604, but it is now only available as single channel OPA604 devices, there are obviously other single channel opamps also like Muses 03 etc.

It would be nice if they also offered 2 x through hole DIP packages to one DIP adaptor board.
That is what I had in mind.
I will get some of these though.
EDIT: Looks like they do. AWESOME

Finishing up a DIYA project to be released this month; it includes the forehead slap "oh duh" realization that it is possible, practical, and perfectly legal to include two DIP-8 sockets on the PCB. One of the sockets marked "SINGLE" in top silkscreen text, and the other socket marked "DUAL". Straightforward design allows the user/builder/listener to plug in and use either a single opamp (one amplifier in a DIP-8, such as LT1122, AD817, OPA627) or a dual opamp (two amplifiers in a DIP-8, such as LM4562, OPA2134, NE5532). All it takes is an extra DIP-8 footprint on the PCB and the ability to connect things together properly.
What about SMD opamps? They're not very interchangeable so they're difficult to swap in and out for experimentation ("opamp rolling"). My approach is to mount them on SOT-to-DIP8 adapter cards and then plug those cards into either the SINGLE socket or the DUAL socket, same as with thru-hole parts.

I made a little companion board to implement this in a neat fashion. It's about 2 x 3 x 2 cm with 2x 3mm mounting holes.

Excellent.
I would have used the 100 Ohm resistor as shown in the original circuit. 10 Ohms does the job though.
I wonder if a C0G cap might be considered superior for this kind of application.

The Glassware diagram shows a 10R.
Isn't it bed time yet Pico?
Fun Fact - Australia has at least 4 time zones (or more) and enough to make me confused, especially if you include Christmas Island:
1:18 a.m.
Wednesday, August 19, 2020 (GMT+10)
Time in Canberra ACT, Australia
2:18 a.m. Kingston (GMT+11)
12:48 a.m. Adelaide (GMT+9:30)
11:18 p.m. -1 day Perth (GMT+8)
10:18 p.m. -1 day Christmas Island (GMT+7)
