BigJHW Posted March 5, 2022 Share Posted March 5, 2022 Hey, So picked up a TecAmp Puma 500 1st gig and spotted a problem that appears to be caused by the fact i'm putting it in to my Barefaced 212T (not an issue that anyone would have known about if they were using an 8ohm cab or a more sensible 4 ohm cab - apparently just a ME problem haha) The Puma 500 is a gen 1 so doesn't have an internal fan looks like putting it through my 212T 4ohm is causing "something" to over heat and sound to cut off. Someone did make a post about TecAmp saying some 4 ohm cabs run "low impedance" which causes the power amp to get too warm and cut out. They said there was a mod of adding a little internal fan to amp which should resolve the issue. I know nothing about electronics so i'd be the WORST person in the world to try and do this but there are some amazing people here on bass chat and i was hoping there might be someone local to Basingstoke Hampshire (UK) that might know how to do this for me and have a part to do it probably involves installing a fan (of some sort) connecting it to the power and probably some wizardry with other wires and bits.. otherwise it's probably going to mean new cabs or selling this amazing sounding bass head and getting something like a markbass tube800 instead.. (which i don't really wanna do) thanks in advance. Quote Link to comment Share on other sites More sharing options...
Harlequin74 Posted March 6, 2022 Share Posted March 6, 2022 Go for the Markbass. I use this and it is very good. Quote Link to comment Share on other sites More sharing options...
Steve Browning Posted March 6, 2022 Share Posted March 6, 2022 Not stalking you. Honest!! This is probably a simple wiring job for any competent electrician. "Amp modder" may put people off responding, as that's a pretty niche request. Your description of the job sounds accurate and probably amounts to a couple of screws and soldering two wires (in the right place). Where are you in Hampshire (I won't visit, I promise!!). 1 Quote Link to comment Share on other sites More sharing options...
BigJHW Posted March 6, 2022 Author Share Posted March 6, 2022 Basingstoke matie.. honestly considering trading it in for an Eich T500 tho haha same amp - but newer and as far as i can tell HAS resolved this issue. gonna wait to hear back from Eich (hopefully) to see what they suggest. 1 Quote Link to comment Share on other sites More sharing options...
ukbassboy Posted February 26, 2023 Share Posted February 26, 2023 So where did you end up with this one? When you say Gen 1 is it the double height version?? Interested to know if there are any issues with the 1U? Quote Link to comment Share on other sites More sharing options...
BigJHW Posted February 27, 2023 Author Share Posted February 27, 2023 Hey there, I ended up at a well know bass retailer where i traded in the PUMA and came away with an Eich T-900 I did speak with Eich to see if there was anything that could be done as it was a "known issue" that they used to resolve for people even on the old TecAmp stuff, but sadly they said it wasn't something they did any more.. They suggested a buying a small 3rd party fan and getting it wired in to keep the unit cooler - but they felt the problem could actually be with the BF 212 i was running at the time and it running below the 4 ohm min load for the bass head causing it to over heat. Something they resolved in the Eich gear but them all having the cooling fan installed For reference it was just an early 1U Puma 500 Hope that helps. 1 Quote Link to comment Share on other sites More sharing options...
ukbassboy Posted February 27, 2023 Share Posted February 27, 2023 Great detail, thanks. Sounds like it is maybe worth avoiding the 500s without a fan. 900w model would be fine as would barely tickle that output! Quote Link to comment Share on other sites More sharing options...

Grab any of the newer Eich stuff and it's all good don't get me wrong with any other cab i imagine that TecAmp head would have been amazing - it sure sounded perfect - thankfully the Eich is just as clean and of course as i got the 900 - MORE POWAH !!!!! (still can't push my BF cab to it's limit tho haha) Quote Link to comment Share on other sites More sharing options...
Ralf1e Posted March 7, 2023 Share Posted March 7, 2023 Glad you are sorted. A computer cooling fan would do that job. Quote Link to comment Share on other sites More sharing options...
nikon F Posted March 10, 2023 Share Posted March 10, 2023 i think the first thing i would have done was see what the cab was running at . sounds like its sorted now so moot point. Quote Link to comment Share on other sites More sharing options...
