The Fender Bassman 100T thread

Yep, I know - it's got to stay. Last time I flicked on an SVT I wasn't happy until I got another. Guess I have to accept the fact that I'm a prime candidate for Amplifiers Anonymous :D. Buying the 610 neo was made easy as I covered it with the telecaster trade-in, so the SWMBO can't play the guilt card ;).

So good an weird news.
I got my 100t back from the shop today and the good news is nothing was wrong with it.....thats also the weird news. The fan and sensor both work. It seems (and the tech showed me the service manual) that according to fender the fan is only supposed to come on "at critical heat" and "most likely will never come on"! So the hot running temp is normal and expected. Strange.

Thats awesome man! Do most tube amps even have fans in the first place?

It smokes the v4bh. Is easily as loud as the v4b, but it goes into overdrive much smoother and less drastically. The v4 goes clean and then all of the sudden it goes full distortion with a very slim sweet spot. This ones sweet spot is quite wide and real sweet.

That is good news, I was a little surprised they had a fan as the old Bassmans never needed one and my Orange AD200 is quite happy working hard without a fan.
On a different note, let me tell you that the neo 610 cabinet is great. I had been unsure about it when I first played it in the shop, but once I had it home and a bit of time it really has impressed me. Looks fantastic, really light and the horn crossover is perfect and smooth. Nails the vintage tone and works great with a bit of grind on the modern/overdrive channel. Will try it with the SVT VR and Orange AD200 at the weekend, but it certainly seems to get the best out of the 100T. You really do get the impression that there is much more clean headroom than my memory of the old seventies Bassman amps, although I can't find any specs on the sensitivity of the speakers. Might also AB it with the Berg 610 if I get time.

yeah im loving my 410 bassman neo. super light and feels really well made. and seriously that blackface covering just looks mint :)

well ive unpacked the super bassman and 810 neo, first impression was heck this cab is considerably larger in all dimensions than my abm 810, and so putting that head on that cab i needed every inch of my 6'2" height, it makes an imposing tower. ive run it at home on 5 master and 5 volume,[the kids told me to turn down as the plates in the pantry where rattling to much!], and it feels like its got good head room in reserve at those settings, best adjectives are warm and thick. dailing in some gain gave a very smooth tube overdrive as you would guess aka the real thing , no o.d pedal required here. clean wise , setting both vintage and o/drive channels to equall eq settings then a/b ing them the overdrive was just alittle brighter than vintage , once again no surprise. i imagine these findings are similar to you 100t owners? On the cab, those sprung handles underneath look handy and arent advertised to much. the cab has 3 baffels to seperate each pair of speakers and a port for each section. band practice soon will let you on how that sounds ..........

Hi Chrisan - yes, when you pick it up the packaging is pretty imposing isn't it? There is a lot empty space inside protecting the cab and it makes it way huge. I actually used my van to drop your amp and cab over to DIs to arrange delivery for Richie as the courier service said it was too big for them to handle!

Well now I'm tripping a little about this. I had noticed the fan never came on when I was playing here at home but I never thought to look at it at rehearsal. I'm just getting a band together and we don't gig for another couple weeks so I haven't used it at stage volume. But I after reading you guys' comments about the fan probably not even coming on under normal use, I checked after rehearsal yesterday and my fan was on. And the amp was not overly hot. I was playing with channel volume 5, master volume 3.75 with a 4x10 Harke, so it definitely wasn't being pushed. I don't know how much time elapsed before I checked the fan as we were in a discussion, but I would think it was well under 5 minutes. So I don't know how much time it had to cool down before I checked, but I think I would have noticed it was hot when I put it in standby.
Also, it's awesome these amps have fans. I doubt it's because this particular design is gonna run hotter than normal, I would think it goes hand-in-glove with the auto bias for extending tube life, as heat is what does them in. But the comment from Fender that you'll probably never see it come on except in extreme heat seems strange to me. I would think it would come on under normal operation, at least rehearsal level, just to help things stay cool as possible

What are you running the tubes at? I would think that toggle would affect the fan coming on or not

I had tried it at 25watts a couple weeks ago at rehearsal, but I was running at 100watts yesterday. I've been overly cautious with it since it is a new unknown thing, and trying to check to be sure it's not running hot. In fact I remember during rehearsal feeling back at the switches and the cage to see if anything was hot, and it never was beyond what you'd expect. But I didn't look at the fan until after we finished and it had sat in standby for a few minutes. Still I really think I would have noticed if it was overly hot when I put it in standby. Like I say it makes sense that the fan would come on under normal conditions, even if the 100T doesn't run any hotter than the vintage 100w Bassman. Just because it didn't have a fan doesn't mean it couldn't have benefitted from one.

I've never noticed my fan come on, but then I have not consciously listened for it. If it is very quiet (and sometimes some can be quieter than others depending on fitting or luck) I would not notice anyway.
TBH I am simply not concerned one way or the other and am certainly not going to let my enjoyment of the amp be spoiled by obsessing over it. It could also be affected by external influences such as the venue, humidity, stage lighting heating up the stage etc and there is a warranty anyway. Just play and enjoy I reckon.

Well with mine I wasnt looking for the fan but it got real hot on the back panel that you couldnt touch it for any length of time and the fan hadnt come on. I took it in and the sensor and fan both work... When I get home ill take a pic of the service manual passage. For clarity, I had the channel volume about 7 and the and the master at 7 with the tubes biased one or two notches cooler and the amp eq'ed "flat"ish for it being a fender tone stack... At this point im not worried, im just gonna play the hell out of it and see. Ive got 4 years and 9months of warranty left if it is too hot. I guess ive always had "cool" amps. My ampegs and orange never even felt warm, and my 300 pro is very well vented.
 
#118
Good point, eyeball, you if there is a problem it will show up well before five years. 7 and 7 sounds pretty full on though. I see we both run ours into the 610 neo cabs. Since I like a clean tone I think if I needed that much push from the amp I would probably be using one of my other heads(I notice you too have a few other heads - and Berg cabs - like me).
As a matter of interest, was there much breakup at that level?
