You can buy IR receiver diodes. What is the amp? Should be possible to find out what system the remote is based on. Then a S/H one, or even a universal remote might do the trick.

Sh17-a-br1k? ;) Hope so. :)

They are 30VA so designed to give 45v at the full output current of 0.33A per winding. 10% over at low current output seems about right. Can you just put a 7v zener in series with the DC into your reg thus dropping 77 to 70? 7v @ say 20mA is 150mW so 1W will suffice as this should handle the...

It's not difficult, just needs a bit of application, thought and effort as you are trying to marry to a heavy curve and you need a solid foundation to fix the TT frame to. Quite simple really. Try moving your straight-edge about if you can as you may find an area that is much less troublesome...

Scribe top rail to fit to wall shape. Use putty, filler or similar to fill gap between rail and wall and fix in place. Make sure it's level along the length and front face is vertical. Put screws through frame into the top rail (pre-drill with a small bit to avoid splitting) and lightly screw...

Like this:

@The Captain carve the thickness (45mm) not the width. IF YOU TRUST YOURSELF with a hatchet then that can be used but bl00dy dangerous IME. Fingers don't grow on trees... Doesn't need to be perfect as the putty will do the business.

If you get some 3 x 2 PSE (that's planed up stuff) then cut a piece just longer than the width of the shelf, along with a couple of 'props' to sprag it off the floor so it's level and at the desired height, then blu-tac it in place with the 2in wide face against the wall. Then, use a block and...

This works well: https://www.ebay.co.uk/itm/264297763592?mkcid=1&mkrid=710-53481-19255-0&siteid=0&campid=5338728743&customid=&toolid=10001&mkevt=1

On the output devices, collectors go to the supply rails and bases are fed with a bias voltage of about 2.1V between them. So, you put have: 100R>npn BE>0R22>0R22>pnp BE>100R. Centre of 0R22 goes to FB network. If something was awry, there was a possibility that I'd have just blown the new...

Removed the H/sink and the mica insulators, cleaned it up and replaced with new ones and fresh Kontakt Chemie paste. Biases up OK with low DC offset on all channels. Measures from 4.2 to 4.7mV bias across each pair of 0R22 emitter resistors. Ran the repaired centre channel for about 20 mins...

No, I meant the amp. Which outputs are you using, switched or direct? Did you try 'phones with mono source? If that was fine then unlikely to be the amp. Probably needs the switches cleaning, particularly those on the headphone circuit. @Operajulian

What kit is it?

Digital volt meter.

Or if you don't have the above, a pure mono recording should be bang in the middle. Check with headphones too.
