So looking on the bright side, an actual crossover and a decent hi-mid driver could be a huge improvement. If anyone can recommend a crossover product or a circuit I will fit one. Thanks once again to @Bill Fitzmaurice and @stevie for sharing your knowledge. It is much appreciated.

I thought I'd better take the woofer out and have a look at the crossover. Turns out that there isn't a crossover as such: the mid driver is parallel-ed off the woofer and has a 4.7 µF capacitor in the positive line. Picture attached. I haven't a clue what effect that has, I'm hoping someone here can enlighten me. I think it's a partially rubbed-out 8Ohm rather than 3, which would match the woofer impedence.

As far as I know, I am the only owner of this combo. I bought it in October 2009 when guitarguitar gave up the distributorship. A lot of basschatters bought discounted Tecamp gear at that time. Unless it was a return before my ownership or gearformusic fitted it, I don't know how this driver got in there. The only people who have worked on this combo since I bought it are Tecamp themselves, who replaced the woofer when it failed in 2011. It's been fine since then, until a few weeks ago. Thanks everyone for the assistance and @Bill Fitzmauricefor the link to that Faital driver, Blue Aran have them in stock so I should be able to get one without any trouble.

This is the original. As far as I know, I'm the only owner of this combo. Ah, I see what you mean. It's possible that the original blew and was replaced before I bought the combo, but it was supposed to be new at the time and wasn't described as B Stock. I can't explain how they wouldn't have fitted an original part. If it's been in there all the time I've owned it, it's lasted 15 years, if I get another 15 out of the replacement I'll be 81 and long-retired from gigging!

I knew I should have done this before putting it back together. That serial number string doesn't bring up anything useful in searches. I just recalled that the original woofer was made for Tecamp by Sica, and I wonder if the hi-mid driver was too. It looks similar in spec to the 4 C 1,5 C P but I'm not sure where I can get one in the UK. https://sica.it/wp-content/uploads/2021/05/Z001920-1.pdf

What's wrong with that? I listened to a lot of songs recorded in the 1920s when I was a teenager. Teenagers now are listening to songs recorded in the 1920s.

My Tecamp Puma 110 combo has developed an annoying buzz from the hi-mid 4" driver, so I think it is on the way to complete failure. There are no identifying marks on the driver and nothing useful except '8Ohms' . I can't find a specification for the existing driver apart from some marketing speak: "The combos feature the new NTM-1 middle-high cone speaker with a Neodymium double magnet system. Working in a sealed enclosure it impresses with a low roll-off frequency and a very flat frequency response, thus delivering a smooth top end far beyond 10 kHz at astounding sound pressure levels." I've tried a couple of emails to [email protected] but haven't had a response, so I don't have high hopes of either a replacement NTM-1 or the CT1 which they now fit. I have found this B&C driver, which has a range of 110 - 8000 Hz which seems to be in the right range. https://www.bcspeakers.com/en/products/lf-driver/4/8/4NDF34 Would this be a suitable replacement driver, or can someone propose something better?

EBS Neo 210 is almost vertically aligned and front-ported. There's a used one in the classifieds if you're quick.

There is a whole world of great lessons on Youtube. I've personally found Geoff Chalmers 'Discover Double Bass" , particularly the beginners section, and Matt Rybicki's channel to be very clear and helpful. I'm sure others will have recommendations if self-study is what you like to do. https://www.youtube.com/@DiscoverDoubleBass https://www.youtube.com/@LearnJazzBasswithMattRybicki

Normally the requests I get are physically impossible. Have you seen the size of a double bass scroll? Once when I had a gig with an Elvis tribute, a guy came up to us and asked if we would do a request, and could we please play 'Blossom Ar$ehole' . Blank looks all round. "Sorry, we don't know that one" . "You must do. It was one of his greatest ever hits". "Can you sing us the first few bars?" "Weel Blossom Ar$ehole what's wrong with me, I'm itchin like a man on a fuzzy tree ... "

Splendid. I can tell you all about my new gig as a piano player in an Irish ceilidh band.

Slice of bike inner tube?

I heartily applaud the modern fashion for writing everything in C and making every deviation from the major scale an accidental.

I agree with you - G# Bb B .

How about a Firefox clone such as librewolf? You might also be able to use containers, although that's probably going to involve some tinkering with the existing installation and I can see why you wouldn't want to do that. https://addons.mozilla.org/en-GB/firefox/addon/multi-account-containers/

Some SGC Nanyo Bass Collection genes there. I should leave the decal, especially if it's the only identification.

I put mine into 4ch mode and use it as a 4-channel mixer.

Alexei Sayle already nailed that one. "There are two kinds of jazz, and they're both crap!"

The bass I've had the longest is my Yamaha BB800, which I bought second-hand in 1979 from the estimable Charlie Carter, who ran the Sounds Acoustic music shop in Chester Rd, Manchester. The instrument I've had the longest is the English concertina that I started to play in 1974. 50 years this year. Kin 'ell.

I've done this with my TecAmp Puma combo for years and never had any issues with feedback.
