'75 Silverfaced Twin

Bias setup complete

Hi gents:

We got that '76 Twin Amp Bias adjustment setup complete…
The amp is ready for the stage tonight…
I hope all works well with it…
It should…





Dale should enjoy this amp…

So, my address is

Well I’m sure this amp is a lot nicer than my Jet City, but I gave my JC its first outing today.

I was asked to play electric guitar at the church we’ve been going to so I figured I’d try the JC. I fronted it with my Boss GT-8 for a bit of reverb, delay and chorus. Used my Washburn semi. (http://www.guitarjar.co.uk/user-reviews/washburn-hb32dm-review/#more-1089). All pretty low volume stuff but actually I was very pleased.

Hi Mark A:

I see it another way…


It’s using the correct amp for the the right stage application…
That’s a beautiful Guitar Mark A… Nice review, as well… :)








I have a Washburn BX-500 Bass Guitar that I use…
Washburn Instruments …

:agree:
:agree:
:)







Bill…

I ain’t gonna stop… I’m gonna run right over there and rebuild that K-720 Amp… :) :laugh: hehe…

Yeah, that Washburn was really cheap (thanks for fixing the link by the way), but it's pretty much my go go guitar. It's so versatile. Does strummy - almost acoustic - through to blues and then rock. Well pleased.

I got the rest of those photos uploaded this afternoon…


Here’s a Quick link to the photo blog of the Amp Repair…


Here’s some photos of the Amp as it was being assembled back in the cabinet, for anyone interested in the Amp…

This Amp repair worked out pretty nice…
AND…
was a great experience, from Start-to-Finish…







Bill…

Looks great Bill. How many man-hours do you think went into it?

Hi Mark A:

I agree with you also…
BUT…
If it were a Vox AC 30 or some model of Marshall Amp I’d have the same respect for the amp…
A Traynor Amp or (any mass manufactuered amp) would have the same interest…I seen many Messa Amps but I’d have to say that Boutique Amps don’t hold my attention…
There’s way too much “Name” connected to the amp…
They are still TUBES…
Well…





I’d say the original owner of this amp took good care of it, OR…
he was a closet/home Musician…
I don’t believe he played many stages with this amp…
The Toilex covering looks to be in too good appearance to be a “Working Amp”…
As wall, I agree with Bob…
These amps should not have casters on them…
As heavy as they are, they should be carried by their owners…
not pushed over door tressels… that renders the tubes microphonic and stresses the Reverb Tank, and all…



Actually, this amp was well maintained over it’s years…
The power supply capacitors were replaced at some point…
By looking at the components, I’d say all the resistors and other capacitors were original as it came from the assembly line… We did the work on two seperate days…
All-in-all we may have about two-to-three hours of time into the upgrade/repair…
Most of the time, getting up-and-current with Dale and a bunch of Chin-waggin, and all…
:)

I replaced the (output tube) screen resistors…
They were not as close to tolerance as I would like to see them…
Leo and I don’t agree with resistors being so far outta tolerance…
Today’s boutique/matched tubes need to see all the components “Matched-to-Tolerance”… so-to-speak…



Back in Leo’s Day… (not mine)…
:laugh:
:p
Tubes were better built…
German, British and North American manufactuered tubes were better built than the tubes of today’s market places…
They didn’t need to be So-Called, “Matched”… Tubes outta tolerence didn’t reach the market place, bacxk then… Hense, Screen resistors that were 10 - 20% outta value were acceptable…
Not Today…
A 470 ohm resistor should be 470 ohms…
Not 490-or-510 ohms…
A Boutique Tube will work better and last longer…
Even at today’s prices…



Back then, tubes were built for the Military…
Not Leo Fender…
:p
:laugh:





Anyway, over in these parts (Halifax-and-Province) we have two weeks off…
for the Canada Winter Gasmes…
So we’ll be back working on the Ampeg Bass Amp and the Fender Blackfaced Bassman Amp…




Bill…

Hi TomS:
I just noticed your avatar… Looks “SomeNice”… :) :O :laugh:

Finally got to listen. That sounds so sweet Bill. Very, very nice.

Hi Mark A:

I’ve been hearing you comment on your Internet /Server where you are…
Am I correct that your bandwidth is being limited when you reach a metered amount ????
There’s talk that the CRTC…a Government Commission is contemplating allowing the servers to add a surcharge on users to maintain bandwidth performance or reduce bandwidth performance when a limit is reached…
As a result, this doesn’t bode well with the taxpaying public over here…
We are not sure just how this is going to “Play-Out” if this rule comes-to-pass…
We’ll see…




Anyway, we’ve got a reply from Dale…
the Twin Owner…
He’s quite happy with how his Twin Behaves on the stage…
:agree:
:agree:
So-he-Says…
This guy has played on some heavy duty stages over the years…
He knows how-and-what to expect from his stage gear…
The thing is…
many of these guys never tell you how their equipment behaves till they want their amps fixed again…
You only get to see them when their amps are broken down…


Anyway, we’ve moved on…
We are working on this Ampeg B15N Bass Amp…
The cabinet is looking pretty good and the speaker and chassis is almost ready to be assembled…The preamp tubes are 6SL7 tubes… They are pretty expensive… SO, we are redesigning the tube sockets to accept 12AX7 tubes for replacement in the amp…
I’ll have photos to update the photo blog on the Bass Amp photo blog…
This Bass Amp is beginning to sound pretty nice…
We’ll have to wait-and-see as the amp restore comes together…

Hi Mark A:

Yeah, never had metered access in the UK but here you buy a certain amount of data each month as part of your broadband package. They start as low as 2Gb a month. I'm on 40Gb and blow it every month. 40Gb is just about the highest domestic package. Download and upload count so as a muso it sucks. It's pretty easy to chew through it with 3 kids and 5 pcs in the house.

Once you hit your limit everything slows right down to modem speed until your next month's allowance is due. I could move onto a package that allows me to pay per Gb when I go over my allowance but that sounds dangerous to me. :)
