It turns out that even living in a big town like L.A. (I obviously live there  Tongue) doesn't get you electronics components easily anymore. What was I thinking?? I go down to a local old-school kind of electronics store and he doesn't have even a 1/4 of what I need. I had Jack's Mouser part numbers on my list. The store owner asked what those were, I told him, and he said "hey, I find myself ordering from Mouser too."

Bottom line... I now have a new order of all the goodies in with Mouser. Guess I'll get into the amp next weekend.

Who'd think getting all the right parts together would be a challenge all to itself?

AS a preliminary sortie to see what I could find here in the UK prior to considering doing the mods, I found it really difficult to source what I need. I'm going to have to try and persuade my amp tech to order the parts for me I think.

by the way, my BOM had the incorrect part for the 120pf caps. Here's the right part:

How important is it to source parts from a 'respected' manufacturer, and what name should I be looking for?

Thanks

I'll go add that to the list. When I was ordering, I noticed that the 120pF cap was something odd and should have questioned it. That's what I get for being in a hurry... oh well. Hind-sight is always 20-20. At least these caps are really inexpensive. Thanks for the heads-up, Jack.

OK, folks. Here's a complete, updated list of all the components (BOM if you will) that Jack prepared recently. This should be all you need to do the mods recommended so far. If somebody notices something wrong or missing, corrections would be most welcome!

It never hurts to have a few extra pieces around. The little devils might come in handy one day.  Grin
