Modern NPN/PNP transistor pair alternatives for BC182/BC212 in audio circuits?

I'm loving the latest Audio Out column by Jake Rothman about analogue synthesisers.  However, many of the circuits call for the BC182 NPN and BC212 PNP transistor pair.  I used these in my first guitar practice amplifier and they were great for audio designs but these are more or less obsolete now.  Does anyone have a suggested replacement that sounds good?

Hi Martin
Great to hear you are enjoying the analogue synthesiser series.

 I'll ask Jake for a comment on the transistors in the next article.

In the meantime, I should make it clear that the purpose of the current series is not to create a state-of-the-art analogue synth, but rather to explain the basics of how they operate using fully working, but (somewhat) basic circuits. The designs are good, but to avoid creating a monster year-long seres of articles we have not gone into super-fine detail, and tried to use cheap, readily available tried-and-trusted components.
Last, but not least, we are hoping to follow up this series with a standalone project that will represent the best of modern analogue synthesisers using an established kit from a UK-based vendor.
Hope that helps

Martin - these transistors were part of a long series of transistors that were all very similar, mainly just with different cases and pinouts.  Elektor magazine used to have a page in every issue called TUPTUNDUGDUS - which stood forTransistor, Universal, NPNTransistor, Universal, PNP
Diode, Universal, Germanium
Diode, Universal, Silicon
They used to specify the above  as components in many projects, which made life very simple if you had a reasonable junk box!  In the page they gave lists of parts which met the specifications for each component.  They don't do this any more (not a lot of projects use transistors now but it's still just as valid.  I was fortunate enough to find a copy of their page on the net here.  I'd think that for most purposes you'd be able to use this as a substitution list for this and other projects.  Many people have linked to it - just put TUPTUNDUGDUS into google and you'll find one.  I keep a copy ready to hand for just this purpose.  Bear in mind that cases and pinouts are different, so you may have to work out your lead orientation if you use a different transistor, but they'll almost always work.  There is a list of pinouts down the right hand side, along with remarks in which your transistors are noted as having an Ic max of 200mA, which is greater than their minimum spec for TUNs and TUPs.  If this is likely to be an issue in your circuit then select parts with similar limits.  But for Audio applications that's not likely.In rare (and I would say very rare) cases, a circuit may depend on a part having a certain gain or power or current or frequency response, but for Audio circuits this would not usually be a problem. And lines like the BC547-8-9 and BC557-8-9 often came with an A,B or C suffix to indicate progressively higher gain types - so use those if you know a high gain transistor is needed.

Hi David,I tried the link and it does not work.
Regards,Richard.

Hmmm...don'cha love the web??  Google TUPTUNDUGDUS and the first link will be from a site called 320volt.com.  Click on that and it will download a PDF to your PC which should then work. For some reason if I post the link it does not work from the EEWeb site.  Apologies...This site http://www.tonyvanroon.com/oldwebsite/circ/tuptun.htm has the same info very nicely set out.This site has the info as a JPG instead of a PDF:  https://vdocuments.net/tup-tun-dug-dus-elektor.html
