Cosmetically, I'm thinking about changing the shape of the apperture in the front fascia... This is how it looks now... And this is my latest idea... It's only a Mock-Up photo but I think it would look more in keeping with it's original form... And would also have the added advantage of providing a place for a single port (if I decided to go down that route). I would very much appreciate everybody's comments on the proposed 'new' shape of the grill.... Cheers.

More great advice... Many thanks... I still haven't had chance to wind it up loud, so I won't even consider porting until I know what it sounds like under load... But according to all the advice I've had from this post is sounds like it would be more trouble than its worth, and also I think that a port would not look right in a cab of this vintage.

It's great.... Just so long as your secretary has small hands! 😉

I was thinking just the other day how small the dots were on my bass... It must be an age thing, as i had to do the 'Tippex' trick on my guitar amp a couple of years ago... Makes me wonder how I get through the day in one piece...

That's brilliant, many thanks for your advice. To answer your questions... At the moment it sounds (to me) ok, although I haven't had the chance to crank-it yet. The bottom end sounds fine but at low volume everything sounds fine! The rear door is great now that I have put some self adhesive door draught-excluder on the joint, the latch & hinges are surprisingly sound. I am getting sthe odd rattle at certain frequencies which appear to be coming from the wire mesh on the original half-moon vents in the rear door. I did blank these off with hardboard (and sealed with silicone) on the inside... Perhaps the mesh will have to go!

I've kept hold of it, the cone and coil appear to be in good order (no rips or drag on the coil)... But I think these were made on a budget, hence the lack of a name plate... I also think that it may well be 16 ohm as most of these projector cabs were 16's.

You're absolutely right! I did have a quick look at the 'maths' of it all and it made my head hurt... The software looks like the right way to go so maybe I'll have to take two deep breaths and try again!

I fully understand that, it's jut a bit of fun for around the house.... As I said at the begining, it will have limitations, I just want it to be the best that it can be. Do you have any advice on size of port or port length?

First off.... This is for home / light rehearsal use.... I'm not expecting to play the Albert Hall with this thing!.... But I would like it to sound as good as it possibly could, given its limitations... And mine! A while back I was given this Bell & Howell 631 projector speaker cab, complete with its 12" Jenson 'fan-frame' speaker and thought it would make a nice little home bass cab project. So far I have swapped the speaker for a Celestion Pulse 12, added a jack socket and plate, blanked-off the two semi-circular vents to the rear of the cab and added a bit of padding to the inside of the rear door, along with some door seals. I also added some 1960's grill cloth that I had knocking around. (which I might change at a later date). I had to increase the diameter of the apperture in the baffle plate as the Celestion was about 10 or 12mm larger but the baffle retains its felt lining. I also had to remove the extruded aluminimum grill as it rattled like a snare drum. Having removed the original grill, I then opened up the lower portion of the front of the cab to match the apperture in the baffle plate as the original design had the bottom of the speaker behind the fascia. To port or not to port?... That is the question... At the moment it's more or less a sealed cab, but quite a small cab, somewhere around 36.3 litres. It's hard to be exact as the sides on the cab taper inwards as they reach the top. I could possibly fit one or two 2" ports in the the front fascia but 'tuning' them would be another area where I'd need some advice. I will probably 'square-off' the front of the cab's opening (see mock-up photo) as I don't really like the 'smiley face' front it has at the moment. The amp for this cab is a T.C. Electronic BAM200... So nothing too heavy or ambitious. Photos... 1 - How it looked originally (not mine as I forgot to photograph it in its original condition). 2 - As above.... 3 - How it looks at the moment 4 - Inside View 5 - Rear View 6 - Mock-up for 'new look' front. So... Your thoughts, comments and advice would be most welcome.... Many thanks.

I was going to suggest a Weller iron, as I've always used Weller soldering irons but after viewing your link, I've just ordered your one from Amazon... It's cheaper than a set of tips for my Weller!

Have you tried increasing the value of the cap on the tone pot?... That would only cost pennies and should make the tone darker as you turn down the tone pot. Changing from single coil to humbucker pickups usually requires changing the pots too as their values will be different.... I'd try changing the cap as it's 5 minutes with a soldering iron and only about £3 from your pocket.... If you don't like it, you can put the original one back in... Hope this helps.

I don't know, all I can say is that my friend told me this more than 10 years ago after a VM gig he went to at the Brighton Dome.

A friend of mine told me about a Van Morrison gig that he went to a few years ago... Van Morrison had just released a new album the week before the gig. He came on stage at the begining and said: "We're going to play the new album for the first set, then we'll go off for a little break and then when we come back, we'll play some songs that you've heard before." So they played the new album for the first set... Went for a break... And when they came back... They played the new album for the second set.... And then went home!
