Usually, the products that are copies of other designs, I prefer to run less officially. So I'm not sure yet if it will be on a website. But you will definitely be able to buy it directly from me. I just have to check it more thoroughly, I didn't even listen to it yet

Please note that none of the current Levinson products is using that buffer. It was only implemented in what is now called, Legacy Products: http://www.marklevinson.com/downloads/index.asp

Default Soldering iron

So tonight I soldered one set of boards except for the LM4780 chip because I think my iron is too big, size and wattage(35watts).
What size wattage would be good to buy?

Maybe this one is better?30w iron

its probably better to get a temperature controlled one such as one of these. that way you can get just the right temperature for fine work and crank it up ig you need to solder something big.

thats just a random page i googled, im suggesting you buy from them, in fact ive never been to that site before.

the one i have is just a made in china one i got from a local store. but it works very well.

Those EL2020s are quite expensive, but look very good. My regular source has them for 6,40 Euro a piece. That is three times as much as I have to pay for the OPA604.

Not really a substitude but recommended upgrade, and that's what Madrigal was installing in (upgraded) ML380S. ADEL2020 has supposedly better specs than previously installed version.

DigiKey carries them at $3/pc (min 50pc qty required).

What would be still interesting is to get MAT02/MAT03 in place of 2210 and 2220.
