Does the centre terminal of the ground lift switch have any wiring to it? Do you have a multimeter? if yes, measure the resistance of that green wire to chassis. If the reading is zero ohms then it is a ground. Solder it back onto the switch terminal. I don't feel that that missing ground is going to change your hum level as the switch in the lift position disconnects the ground anyway. Are you using the DI to connect to a PA?

In my mind I find it strange that people obsess on the noise a fan makes. The solution is really simple: if you can hear the fan you're not playing loud enough!!

Ampeg do make good sounding bass amps. I love my Sixties B15NF. Every time I play through it it makes me smile.

I had a an EB0F in the sixties. That was an EB0 with a built in fuzz box. The fuzz was terrible! The bass was stolen from The 21 Club in Liverpool. I replaced it with an EB2 which was also stolen. Earlier I had a Hofner Violin Bass stolen in Widnes, Lancashire. <sigh>

Didn't they used to be called the EB0 for the single pickup and the EB3 for the two pickup model?

Put the amp with the noisy fan into another room and close the door. A couple of long cables for speaker and instrument and you are away to the races!

@ahpook I hope the amp serves you well.

Sigh!

It was worth a try.

Try linking the send and Return with a short signal cable. See what happens.

I hope the new amp gives you long and faithful service. If the 15 is not an Ashdown product make sure you check that both cabinets are working with the same polarity otherwise they''l fight all night long. The battery test will allow you to check this. Also make sure the combo will handle the impedance of the 15 in parallel with the unit's internal drivers.

As a man with a newly pregnant wife I naturally needed more money. I met her at a gig called Nalgo, which is somewhere off Queens Drive in Liverpool, on June 06 1968. We were married April 26 1969. Fifty four years later we're still together. As for tone, the Leak through a Marshall 4x12 was far better than a Bassman through the same cabinet. I am really not a fan of the Bassman.

Not really as I was moving to a job in South Wales and wouldn't be playing for a long time.

in the late Sixties I bought a Leak TL50+ for 5 Quid. I built a single ECC83 pre-amp for it that plugged into the pre-amp socket on the leak which provided the power. The circuit I used was essentially the Normal Channel of the Fender Bassman. It worked very well and it was the best sound I ever had playing in the UK. The Cathode biased KT88s really impressed me. When I left the band to get married the bandleader asked me if I would trade it for an actual Bassman. I did as I figured the Fender would be worth more when I sold it.

So @msb is she married? LOL She sounds like a keeper!

Sometimes you leap before you look!.

A thing to remember is that if you want to be twice as loud you'll have to increase power by a factor of ten. To buy a pair of 2x10s and then strangle them with a low power tube amp will simply not get you anywhere. You have to balance the capabilities/needs of your speaker cabinets with the power you give them. I haven't used 30W amps since the Sixties! That said I do use a full tube pre-amp to drive my power amp.

I still say that the 2x10 would sound better on its end portrait style. It's even got the feet for that position.

Go on my brother, you know you really want to! And a happy Canada Day to you!

For me it was the first time I played through an Acme 2x10 three way speaker cabinet. I bought one and loved it so much I bought a second. Then two more! LOL Mine are all 4Ω and I drive them nowadays with a 2KW capable Class D power amp.

So all's well then ends well! I'm really pleased that you sussed it out.

I have read through a couple of versions of the owners manual but neither mention the fan. As a guess from articles I have read I would think it should start on power on. If you can reach the fan see if the impeller is free to rotate. It could well be seized. Have you had the amp on long enough for it to get really hot to see if the fan is thermostatically controlled?

I worked up a sweat just thinking about moving that beast!! Glad you got it working again.

I hear you guys were a little warm on the weekend. We had a beautiful weekend. Sunny with a cool breeze and about 20 C. s
