In the very early Seventies The band I joined had bought a whole whack of Orange equipment. I played my bass through said amp and an orange 4x12. Handled it just fine though I was just using a four string Precision. How the set up would handle a five or six string bass I can't say.

First question: Does it work with headphones? mute switch is in the play position?

Tylenol works, we swear by it.

Just for interest, when the amp is in operation do you see a faint blue glow inside the output tubes?

No argument here!! Just move on. There's an old saying: 'None so queer as folk'.

The other side of the coin is that he may have had to deal with many similar calls from other potential buyers and was fed up with the whole sale. That said, he should have been willing to supply the serial number of the unit he is selling.

Speak for yourself Joe!! LOL

I assume, being an Electrician, that you have a Digital Multimeter. In case you are without: bassman_135_sch.pdf

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 Enjoy1

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!

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

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.
