Thanks for that. Think I'll just get some MPF102 and J201's as recommended.

Could I get some guidance on how to select 'equivalent' transistors, for example where a J201 or MPF102 is specified but not available. Apart from just googling 'J201 equivalent', is there way to select based on specs in the data sheet? At present I am planning a preamp to go in front of my TDA2003 amp.

Small bass amps are sometimes recommended for cleans. Also check out some Steel Guitar forums.
They often favour clean SS tones with Peavey and the Roland Cube range often coming up (though the latter use modelling a lot).

The ones I have are a few years old and Ni-Cad. I was using them to power a TDA2003 amp drawing up to 500mA. My hungriest battery driven pedal draws 30mA and the rest are single figures.
Maybe I just need a newer set of batteries. Worst case I leave a pedal powered on overnight and need a new battery.

Are Rechargeable 9v batteries a viable option for pedals?
Just asking cos I have some, and I broke my fx power supply. The ones I have claim 350 mAh capacity but interestingly the only major brand ones I can find are Duracell with 170 mAh. Are the claimed mAh values reliable in your experience?

I neglected to add reverse protection to my LM386 amp and broke. It is basically the Little Gem/Smokey amp. https://goo.gl/images/3dqb9b It powers on but no output. I am checking all the caps and the IC. Anything else I should check? What type of diode should I (have) use(ed) for reverse polarity? Sent from my SM-G930F using Tapatalk

Surely the Tube Sound happened by accident. Tube amplifiers were used to make guitars louder and they did. Then SS amplifiers were used and they also made guitars louder using smaller components and less energy. But they sounded different. Why should we strive to make them sound tubey?

The mains adapter that worked has now died. Any tips on how to buy a new one that is not noisy?

I would. I don't know the actual product but I've often bought stuff that 'sounds terrible' and been delighted with it. Even as a cab it would be cool. Stuff like sealant/glue around speakers should be easy to fix. Maybe some say 'sounds terrible' because its solid state.

In which case they may sound a bit like my diy tda2003 amp so probably not worth my buying one. Looking for something to feed my diy 1x12 cab. At rhe moment I'm using various pedals with my diy amps and happy with that for now. I also play a lapsteel BTW.

Just because they use a TDA2003 does not mean it will sound anything like your amp at all. By definition, chip amps do not color the sound. The "sound" of the amp is defined by the preamp.
OK fair enough. Havent seen them in shops to try out but planning to buy or build something for my 1x12 cab Sent from my SM-G935F using Tapatalk

Hey some nice blues riff there 
BTW, looks like you are driving a hifi type speaker box,, if so then be aware they are woofers and generally have a low SPL,, a real guitar speaker will give a much bigger sound,, louder per watt of input.

A friend has a 12" guitar speaker I can use. Time for a bit of joinery I think
Sent from my SM-G935F using Tapatalk
Finally did the joinery ( takes me a while to do stuff!) I now have the amp and some pedals powered by a single PS in a case and going in to the 1x12. Plenty loud for home use and a great platform for bigger amp builds. Speaker good for up tp 80w. 1w amp and pedals into 1x12 cab https://imgur.com/gallery/lKMg7CRSent from my SM-G935F using Tapatalk

Problem solved. I changed the mains adaptor supplying the pedal power supply. Noise now much at unacceptable level. Thanks again for your input. it stopped me going off om a fruitless and maybe expensive tangent! All for the price of four 9v batteries.  Sent from my SM-G935F using Tapatalk
