Here's my situation--
I'm a novice with some instructional material (G.Weber book and video), a new DMM and a roomful of amps either in need of repair or in need of general maintanence (caps, tubes/bias, 3-prong cord) and modding (cap upgrades, tone stack experimenting, two channel reverb). I'm really wanting to learn a bunch and do a bunch.
What I need is a shopping list of caps and resistors that I can buy at one time to cover a bunch of needs and whims so I don't have to be putting in an order for $3 worth of stuff that I might need to start or finish a particular job. And what I'm hoping to find is a dealer (I've got a list of links to most of the main guys who deal in this stuff) who somebody here can recommend as a good guy to call, shoot the shit with, hear my list of projects and put together this shopping list for me within a stated budget (I dunno--$30--50? maybe more with a set of filter caps, maybe more if I'm talked into it). So I need someone I can trust (important, of course) who has the patience to work with me and hear my needs as I 'set up shop'. And of course I'm not looking for free advice from him--I'm looking to put together an order.
Anyone in particular come to mind that any of you would recommend who would fit the bill? |

There are two larege electronics companies that I use, and they will sell pretty much any quantity of anything, (business being what it is). One is Newark Electronics,(I can't seem to find the address), and the other is Allied Electronics, see address below. They take phone orders, and accept credit cards. They cater mostly to the industry, but try them out anyway. The trick is to get the catalog number for what you want, and that can take some work, like getting and reading the catalog. Good luck.

| Hey thanks Peter. Yeah, I've got Newark bookmarked. But what I'm looking for is a tube amp specialist who can tell me "oh, you're gonna want a half dozen of these orange drop .47pf doodads if you're messing with the tone stack" kinda stuff. Looking to collaborate with a seller who can put together a package with me without pushing stuff on me that I don't need. Maybe I'm being too naive in trying to operate this way but....I repeat my question----does anyone have a dealer that they think highly enough of that they'd trust him in this way? |

| Do a search for "resistor assortment", or "capacitor assortment", and you'll come up with many good sources. |

Hey Donny---I'm usually a full-on Google head but it just didn't occur to me this time. Yeah, there's some options there. Thanks.
Mark--I certainly know Pagano by name and rep. And part of that rep is some ungodly per-hour rates for bench time. I gather he's pretty much top dog in this back-water town.
I am real grateful for the email help. With a little bit of kind help I'm going to be able to get started and then I'll gain the confidence I need to take it from there. |

Everytime you have to buy a small part, buy 3 or 4 instead of one. Shelf life on most every part (except some electrolytics) is many decades. I'm still fixing stuff with parts I bought 40 years ago...back when resistors were 5 cents, capacitors were 15 cents, 12AX7A's were $1.50, and 6L6's were $3.75!
Dem was de good ol' daze. |

OK--I'm putting together an order from you at those prices. Got anything else to sell for 60's dollars?
I got the same advice via email about building an inventory by ordering multiples. Good idea. |

Hi John,
Check out prices for caps and tubes at triode electronics in Chicago. Their prices on Sprague Atom electrolytic caps are usually
cheaper(smaller values) than you can get from Mouser Electronics. My places for parts are: www.mouser.com www.tubesandmore.com www.triodeelectronics.com www.digikey.com www.hoffmanamps.com
Triode and Hoffman are very fast,digikey and mouser right behind and tubesandmore a little slower because they're in Arizona, but they carry some cool coupling and tone caps made by Mallory and Audience. |

Sounds like you may want to (or already are) lurking around some of the amp building sites:

hmmmm,
I am not so sure there IS a small set of parts that would satisfy your needs. Repair of amps, unlike many think, is not repetitive and an ass'y line approach, as each one can be, and usually is, completely different from the last one when it comes to repair.
In fact, repair of anything is one of the most difficult things when it comes to diagnosing root causes of troubles. Replacing parts is the easiest part. But finding WHAT is causing what the customer is complaining about, can be one of the most elusive things one can encounter.
And the fact that there are sooooooo many different sizes and types of every thing used in amps, I would be extremely hard pressed to come up with a "kit" of parts that would fit the discription you gave.
In all my years of working on and sevicing amps, I rarely ever replaced a resistor. I did replace a slew of speakers, switches, controls, pilot lights, power silicon rectifiers, fuses, power cords, transformers, tubes and transistors.
Also, a few caps of course; and ocassionaly a filter cap (electrolytic). But there are sooooo many different values and types I just could not venture a guess of what would be best to keep on hand.
But I do wish you much good luck; much success and may Jesus lead you in the right way,
