/diy/ - Do It Yourself

I'm a beginner looking to build the pre-amp pictured after it was suggested in the previous thread.

I'm planning to run it from 2 9V batteries in series. Would it be able to drive headphones (32 ohm superlux hd681). What kind of capacitors should I use? (electrolytic, ceramic etc) How would you recommend I build it? I've never done a proper circuit like this so don't know whether to use a breadboard or perfboard or whatever else so any advice on that or anything else would be appreciated.

I have also started to look into poweramp options and found 2 ICs which seem to fit my requirements (practice amp), LM2876 and LM3886. The 2876 seems more straightforward since it is a mono chip but seems harder to find. The 3886 needs to be bridged which I'm not too familiar with though I have found ready made schematics (https://www.digikey.com/reference-designs/en/audio-amplifiers/106))
Any ideas on how to power this would also be welcomed. Thanks
