Ok - thanks for the offer to help - I'll get back shortly with what I find. I'm using highest gain setting +20db
Let's see if it's possible to resolve some of these issues. Find out which opamp is in your LC. What gain setting are you using?
Hi, highest gain setting. The opamp appears to have been scraped or rubbed to remove markings - but I can see 45EXY on it. Here is a photo.
any recommendations? thanks.
Thanks for the tips, I'm familiar with them, but I choose the lovely cube because it's the one I would really use out of this three, but I was thinking about http://www.ebay.com/itm/Headphone-Amplifier-kit-Diy-Base-Lehmann-AMP-Circuit-/120764992343?pt=LH_DefaultDomain_0&hash=item1c1e278b57 this one, it looks like an inexpensive firs project for practise soldering.
