Progress pics: "Winter is Hell" Project #1

feeds@yuku.com (Andy ZZ) — Sun, 08 Nov 2009 20:11:43 GMT

Well, just past half way through this project. It's a custom tolex inlay cab to house an old 62 Concert Chassis.
I hope to finish her up this week.
She will be loaded with three 60's vintage Jensen C10N's.
What do y'all think? (Gonna make a matching shirt, with airbrushed dragons, and probably a tolex amp cover)

Reading Tube Specs

feeds@yuku.com (jbmojo) — Sat, 07 Nov 2009 21:39:18 GMT

This will sound dumb but how does one read tube specs? I see things like "Ia(o), Ia(b). Is that the current draw at idle and full load? What's a good link for a rosetta stone on tube specs?
Some of the figures I see do this number on me-

Bass Effects

feeds@yuku.com (jbmojo) — Sat, 07 Nov 2009 09:34:17 GMT

Whatcha like to use for bass effects? Me, it's a Fuzz Face, Vox Wah Wah, Vox Distortion Booster (the kind that plugs into the output jack on the bass), and an MXR Phase 90.

A Tale of Two Chokes

feeds@yuku.com (SG123) — Fri, 30 Oct 2009 19:52:03 GMT

Weber sells part #W014684 that is described as "Choke for Tweed Fenders" 5-8 Hy. 200ma. 125 Ohm.

They also have W022699 which is more or less a Fender 125C1A [ 022699 new part # ] equivalent
9 Hy. 120ma. which is about half the price [ and half the size/weight ].

Both have #22AWG. leads.

Is the larger choke overkill, or is there something unique that makes it "better" for tweed Fender applications? I've seen original tweed '59...

Fender 600 board guide

feeds@yuku.com (jbltwin1) — Fri, 30 Oct 2009 06:12:16 GMT

Anybody here seen a circuit board layout or drill guide for a point to point for the new champion 600? I'm building one for myself and am using an old little pa chassis with it's transformers for a base. The only difference will be that I'll be using a tube rectifier for my supply. Wired it up yesterday for a low end test just to make sure of what voltage I'm getting out of the rectifier and it's right on with 370v with todays power and unloaded. I'm just lazy and...

Scorched PCB ?

feeds@yuku.com (retrorod) — Thu, 29 Oct 2009 06:18:28 GMT

Hi, I am attempting to fix an amp module board for a Rhodes electric piano. It is the 80 watt suitcase model. A resistor next to the transformer flamed up and scorched/charred an area about the size of a quarter. It burnt through the outer layer of the board exposing some of the 'honeycomb' interior of the board. That part is 'dime-size'. I have cleaned up as well as I can. The question is...after I rebuild the traces on the back and install new parts can I expect more...

Trace Elliot SM Series Output Transistors

feeds@yuku.com (jbmojo) — Wed, 28 Oct 2009 07:55:07 GMT

I've got a TE SM200 and an SM600 and the schemo shows different output transistors for the different models, SM600, etc. Can you change out the stock ones with the different power ones, and if so, would they need additional/less heat sinking? Just curious since I don't see any other apparent differences between the two should I decide to change the power output on one or the other for some reason.

Ac30cc

feeds@yuku.com (Andy ZZ) — Tue, 27 Oct 2009 08:00:33 GMT

Well, I've had a few of them on the bench, and I cant stand it any longer, I'm gonna get one.
I had a 60's real AC30 restoration job a few years ago, and when she was finished, I heard what everyone was talking about regarding these amps. (yum)
Later, I had a few reissues come in for minor repairs, and while it didn't 100% nail the tone of the real deal, it came close enough for me.
I cant afford the hand-wired machine, it'll be the cheep chinese model for...

12AX7 vs. 12AY7

feeds@yuku.com (fredg) — Sat, 24 Oct 2009 15:49:55 GMT

I'm wondering if I can drop the gain on 1/2 of a 12AX7 to get it to around the gain of a 12AY7 (having, let's say, 100K plate resistor, 820 Cathode R ) by messing with cathode resistor alone?

I'm in a situation where I have one socket and I'd like to have 1/2 12AX7 in one half and a "simulated" 12AY7 in the other half (i.e, an extra gain stage driving a 12AY7-type Tweed first preamp tube) - all by using one 12AX7. Is it do-able?

Thanks!

KT66 heater current

feeds@yuku.com (StoSoStu) — Fri, 23 Oct 2009 00:33:57 GMT

Is anyone aware of a current manufactured KT66 that only draws 900 mA of heater current, like the original Mullards? I have some QUAD amps in that need new KT66s but all the current manufactured ones I look at draw 1.3 - 1.6 A of heater current and the owner is worried that the extra current draw will burn up his PT. The ones I have looked at are Gold Lion, Shuguang, and Saratov which all draw too much heater current. I couldn't find the heater current data for JJs, and the owner...

Music on the .net

Check out this link and keep in mind that the music changes from DJ to DJ, but I hope some of you enjoy it. They have a live feed and play stuff you probably won't hear otherwise. Just remember that the styles change every few hours when the shift changes. Right now it's old R&B/soul, but that's @ 8:13 CST, it'll change in a little while.

Aside from the plate resistors, what other parts should I change on one of these to keep 'em from burning something else up?

Rickenbacker Guitars.

feeds@yuku.com (Tech21) — Tue, 20 Oct 2009 19:18:41 GMT

Well, I now own not 1 but 3 Rickenbackers.

1... A 1994 Ric 330-6 in FireGlo
2... A 1996 Ric 360-6 in MapleGlo
3... A 2008 Ric 360-6 In MapleGlo

And they are still the only guitar that you can play the start chord to Hard Days Night on and it sounds right.

Did Rickenbacker ever make any Valve amps of note?

Cheers

Hiwatt 50w. Hylight Electronics - Early 80s

feeds@yuku.com (SG123) — Tue, 20 Oct 2009 19:15:49 GMT

My friend has one of these, and a 100w. as well from the same era [ that one's signed by Harry Joyce ].
This is the two input, printed circuit version - and they are not the easiest to work on.

It has the large filter cans inside the chassis. I replaced those a few years ago, but the Bright Volume pot finally bit the dust. Of course it's soldered directly to a separate PC board with the rest of the pots and preamp components at the front - solder joints underneath....

Overseas shipping

feeds@yuku.com (jbmojo) — Sat, 10 Oct 2009 16:58:15 GMT

What's the best way to ship overseas that doesn't cost an arm and a leg? I need to send a PT to the UK for a re-wind and so far it looks pricey as hell.
