Marshall 3315 missing parts???

[turk 182]

i would go with the 175 as the diode test function is valuable for semi conductor testing.

will these work with the 175?AEMC 2152.01 Leads with Test Probes and Alligator Clips for the 1026 & CA7027, Set of 2, Colour Coded, 4ft-

ok, I found a used 175 on ebay for just under $200. There are several cheap test leads with clips, here is a link. will these work?
Multimeter Test Leads Kit Banana Plug with Push On Alligator Clips Precision New 783971354258 | eBay

 

[turk 182]

those should work. with respect to clip leads i was thinking something more along the line of these as they are more multi purpose Blocked

 

[412know1seeks]

I just ordered them. The Fluke showed up today...fast shipping. It came with a standard pair of leads. Now how do I test that transformer?"
Come to think of it, I have a pair of those clips already with my automotive stuff I could use for now.

 

[turk 182]

DBT schematic?
testing your transformer is as simple as connecting it to your DBT and measuring the voltage of the disconnected secondary which should be approximately 32 V AC between either yellow lead to the black of the transformer secondary or alternately 64 VAC across the two yellows.


it's good you have clip leads for this test...


sorry for not getting back sooner but Father's Day found me rather busy...

 

[412know1seeks]

you don't ever have to apologize to me for anything. I have detailed picturesf of the dbt. my art work is that of a 4 year old with a crayon. So, once agaln, White wire comes from AC plug and goes to pic 1 double AC socket with broken jumper contact 1. Red wire goes from contact 2 to the switch, contact 1 in pic 3 then red wire at contact 2 goes back out to AC wall plug. Pic 2 is the other side of dual AC plugs with jumper in tact. Light bulb plugs into either socket.

DBT schematic?
testing your transformer is as simple as connecting it to your DBT .

You mean just the transformer? Like blue wire in one side of socket, brown wire in other side?

 

[turk 182]

ok the DBT is wired correctly.


is the transformer not wired to the IEC socket?

 

[412know1seeks]

IEC socket? It is mounted in the amp, connected to the UPC socket. The yellow and black wires are not connected. Yes, the IEC SOCKET where the universal power cord goes, it's wired to that. So it's ok to turn the amp on? The power won't go past the transformer as long as it is not connected. And which bulb do I use?

 

[turk 182]

60 watt is generally where i start, with an unloaded transformer as low as twenty would work, the series lamp is there as a current limit in case of an inadvertent short.

 

[412know1seeks]

looks like I'm going to have to use a 40 watt, I only have a 40 or 100 right now

 

[turk 182]

go with the forty.

 

[412know1seeks]

Well, after 2 days of trying to figure out why I can't get a steady voltage reading to the DBT, i'm about ready for a rubber room. Let me back track a little. Ok, I could not get a steady reading on any setting and was starting to think the transformer was bad, so I decided to do some damage control and check to make I was getting proper voltage to the DBT. I was using a bad ac outlet, so I found a stable one, but when I plug the DBT in, I don't get more than 10 volt reading that fluctuates down to miliivolts, why? I went as far as to replace the used ac plug sockets and the switch, but nothing was better. The plug and appilance cord that I have wired to the romex tested at 119 volts. That is wire nutted to the 12 gauge #1 house wire that goes to the plug outlet of the DBT. That is where the problem is. How do I fix this?

 

[turk 182]

wish i where there to help you sort this,it only takes one bad connection to mess up the works, with a lamp/bulb connected you should be measuring full line voltage at the outlet of the DBT.

is perhaps your lamp socket faulty?

 

[412know1seeks]

I just tried hot wiring the DBT and eliminated the switch. Nothing. I got 3 questions.
1. should the light bulb light up if plugged in by itself?
2. Should the fluke show any reading when not connected to any thing?
3. What setting should the meter be on? I have it on auto V which is the 2nd click up from the off position.
4. The signal flow on the DBT should be plug wire in screw 1 on the dual outlet with the broken jumper, then when something is plugged in signal goes to the other side of the outlet, goes across the jumper through the light bulb and exits through the wire out to the plug, right?

 

[412know1seeks]

perhaps, I didn't plug in the bulb yet. Duh... I'll be back.

 

[turk 182]

1. no
2. that would depend on setting.
3. AC volts
4. sounds correct but i can't verify that, i'm not there!

 

[412know1seeks]

I think it would be best for both of us if I placed an ad on craigslist for a electronics student and hire him as a tutor to help me with the little stuff, like this.
Yes, I have on AC Volts and if keeps counting millivolts out of thin air. I think I have to return it.

It’s normal for multimeters to count with nothing attached. I believe they’re picking up RF fluctuations in the wire leads. That itself doesn’t mean something is wrong with your meter.
