Simple cap discharger. Never short the caps to discharge them. Get a 10KΩ 2W resistor and two lengths of insulated wire. Solder a length of wire ti each end of the resistor and cover the whole shebang with heat shrink to insulate it. Connect an insulated Croc clip to each end and you have a cap discharger. Connect across the cap and it will quickly and safely discharge through the resistor. QED

Edit: I changed the resistor power rating because a 2W resistor has more robust leads so making a stronger assembly.

Thank you for dropping by Stuart. I'm certain that members will appreciate any information you can offer.

These amps have a very simple schematic - pretty much standard Fender through much of their tube offerings. For interest what seems to be the problem with the amp?

It can't be much good. Look it's full of holes!! LOL

You must remember that 'volume' is logarithmic. This means that if you are wanting more volume, to get twice as loud as a 100W amp you have to increase power by a factor of ten. Thus a 1KW amp will only get twice a loud as a 100w amp.  Using that increase in power means that your speaker systems need to be able to use that power without failing. Their impedances would also have to allow the amp to supply it's maximum power.

The amp I use for my bass is a Class D Stereo power amp fed by a tube pre-amp I built for that purpose. My cabinets are Acme Sound B2 models. Impedance is 4Ω each. I connect them one each channel in a vertical 4x10 configuration. If I use all four of my cabinets, my amp will supply 1000W per channel at 2Ω. 

Which is why I quoted what I did!

Both valves listed as 12AX7 (a standard valve ...but genuine parts preferred!) 🤔

 

Or ECC83 even 7025 which is a low noise version of the 12AX7..

Try the valve before screwing with anything else. 

Good advice from an expert!  

When I was ready to order my Fretless the idea of that massive expanse of black ebony scared me so I had the fret lines put in. LOL

Now I don't even think about it and the bass has become my favourite.

MacGyver would be proud!

You saved me some money too 'cos I was considering buying the parts for you and shipping them to you at my cost. What's a couple of hundred bucks between friends. LOL

Praise the lord - a resurrection has happened!

@MikeStockport One of my brothers in Liverpool mentioned that Manchester was hit by a tornado. Say what???  if this is true I hope you and yours are all safe and sound. 

I'm just glad you got your problem sorted.

By any chance does the Munson have a built in pre-amp? If yes change your battery. 

Keep the Genz Benz. It's my understaffing that Agedhorse is still servicing them when required.  That's an important consideration.

I have used stereo power amps for years in my PA systems and my bass amp. I've never felt the need to Bridge any of them. You really don't have to use both channels. Just use one side by itself.

Looking again I see the link leads to TCH Trans Canada Hardware with an office here in Toronto.  If you wish I could buy a pair and send them over to you. We'd need to sort out the money first. $22.50 Canadian each . I don't think that the postage would be anything near $180.

The problem with buying anything from the States is the huge shipping costs. Even here in Toronto I won't buy ANYTHING  from over the border for that very reason.

I hope the SpeakOn sockets are all the four pole version. They are, after all the standard connector.

Fair enough. I did try a quick search on their site but came up empty.

So try Peavey. At worst they can only say that the trim rings are not available.

Why not just try Peavey in the States? They own the Trace brand now. Perhaps they have the proper port for your cab.

I use SKB products for all my rack equipment and my 'big' PA. No complaints about their quality or protection given. 

If you are using the new cabinet with a 2x10 combo try to stack them so that the tens are verticaly aligned. Doing so does make  difference. out in the room and you'll hear yourself better.

Make sure, using the battery test, that both speaker sections are working with the same polarity.  Otherwise the cabs will be fighting each other all night long!

I'm glad you got your problem sorted.
