2510

[jamesc Modesto, CA USA]

Considering 2510 in non working condition.

Machine powers up, lights come on and record player turns, but record selector is not working.

Getting into it at a pretty reasonable price but does anyone have any insight to this particular model that I should be aware of? I do not see it in any of the threads.

Thank you

Hi James,
Not 100 % sure, but I think all WurliTzers, starting AFTER the "2000", with xx50 as their model number were 50 record--100 selection versions, of the 200 model with the same number --In other words, a 2150, is the smaller capacity 2100 phono. Only difference was the price, ability to be taxed less, or to be used with "100 wallboxes" in a location. Ron Rich

Thank you Ron!

Sorry Ron, the model 2150 is a 200 select machine (100 records).

The 2510 is a 100 select machine (50 records).

Hi Marty,
Thanks for the correction ! My thinking was the, "00" models were all 200 select-- the "04" were all 104 select and the 50 models were all 100 select. Ron Rich

Hi James,
I don't think that the 2510 would be any more difficult or any easier to refurbish than any Wurlitzer of around this era (although the Cobra cartridge was no longer used on the 2500 series mono variants). If the cosmetics are OK, I would see no reason not to take it on.

Thank you guys, appreciate the information!!

Norman, looking at the manual it appears they are calling it a 2 channel, but from what I gather its not stereo but 2 channel meaning 1-12" driver for midrange and 1 for bass? Its a bit confusing, and a 5" driver.

Seems the 540 amp was mono using the common 6L6 and the 2 channel 542 is using some obscure type output tube.

So, I gather it is not stereo?? But some hybrid or early version of 2 channel , not meaning 2 channel stereo?

I think the simple answer is that to achieve stereo would require the use of external speakers. The 542 uses 6973s - not particularly obscure, Electro Harmonix produce these. The mono amp would be much easier and cheaper to refurbish though!

Hi Guyz,
IMHO--"Stereo" is hype when used in a jukebox ! Unless you have excellent ears and are standing/sitting BETWEEN speakers, no one can tell if a jukebox is "mono", "stereo" or "quadro" ! I have installed "a million" jukes in locations, turned up the volume when playing it for the first time and asked "people" in the location, and been told "It sounds wonderful--really great stereo--" Only thing is, ALL were ALWAYS, connected in mono !

Totally agree on the mono 6L6 amp.

Very interesting stuff, I have built PP and single ended tube amps and been involved in tube audio since mid 90's but never recall seeing this tube. I would have thought that they would use a 6BQ5 or 6L6. I wonder if it has to do with this being  German MFG? Or could be the 6BQ5 was not made yet? 

Anyhow, ...the 6973 is interesting .. learn something new everyday right

Hi Ron,

Agree,

My only concern with "stereo" is that some of the Motown 45 tracks as an example, use discreet audio on either the LR channel.

So if the 2510 is creating gimiky "stereophonic" by having 2-12" woofers and a 5"mid when in reality they are playing one track with 2 separate frequencies like an electronic crossover, the music mentioned will not be properly reproduced.

That would not be a good thing for me.

The 6973 was very widely used in US produced jukebox amplifiers - all four major manufacturers used it. The 6BQ5 is what we in Europe call an EL84 and would be commonly used in Europe instead. For example, the Rock-Ola 1475 US stereo amplifier uses 6973s but the European version assembled by Nova in Germany uses EL84s in a European manufactured amplifier. There is an old B&W film on YouTube showing vacuum tubes (including EL84s) being made at Mullard in Blackburn, England (search Mullard Blackburn if interested). Incidentally, the 2510 was not made in Germany but by Wurlitzer at North Tonawanda.
