Tube power stage vs Class-D (effective power)
Tech21NYC replied to Paddy Morris's topic in Amps and Cabs
You have it backwards. SS amps are more linear. What you are describing is the tube amp starts to saturate and "compress" more when turned up. That provides a bit of a cushion to the sound whereas the Class D amp will just get louder. With SS amps there is no output transformer. The wattage changes with impedance. See the specs for our 1000 watt Class D dUg Ultra. 1000 Watts RMS minimum, @ 4Ω 600 Watts RMS minimum, @ 8Ω 300 Watts RMS minimum, @ 16Ω Many commercial SS amps are rated at 2 Ohms because that's the biggest number. The only time I ever blew up a power amp was running at 2 ohms. -

I've not been very active on here for a number of years so didn't know Sam. However, I've just read the depression thread and it's heart breaking. Whatever the cause of her passing to be that unwell mentally is awful and must have been terrifying for her. It's very upsetting. Rest in peace Sam

help with working out how much wattage i need!

No. That's the myth of underpowering, which like Nessie and Robin Hood just won't go away. -

I’ll consider a reasonable offer on this. I could really do with selling this (and a few other things) as I’ve been signed off with stress due to my son’s mental health issues and will go onto half pay at the end of next month due to having already had so much time off for cancer treatments! It’s forcing me to take a hard look at my gear.

Tube power stage vs Class-D (effective power)
Tech21NYC replied to Paddy Morris's topic in Amps and Cabs
Actually it is. From the spec sheet. Wattage 200W into 4Ω (Simulates 85W Tube Amp Performance) Speakers Two - 12" Jensen® N-12K Neo Total Impedance 4 ohms It makes sense. You want more available headroom when using the SS amp vs the tube amp. Coming from the sound reinforcement side of things the basic rule of thumb was always doubling the amount of power in relation to speaker wattage. ie 1000 watt of speakers use at least a 2000 watt power amp. I found this out the hard way by constantly blowing tweeters in my PA tops because I was using an underpowered power amp. With musical instrument amps it usually goes the other way. A 300 watt SVT is paired with an 800 watt 8X10. A 100 watt Marshall will be used with a cab rated at 200-300 watts. Of course this begs the question what is accomplished with with all that complex stuff under the hood? A lighter, less expensive amp that has more flexibility and no maintenance other than software updates. The repair and reliability is hard to quantify at this point. Digital amps usually can't be easily field serviced. If the processor goes out it needs to be replaced etc. We do some repairs on the Class D power amp modules in our amps but it's usually more cost effective to replace the module. While tubes became an obsolete tech in the 1950-60's and have their own set of drawbacks they are still being made. The original Line 6 AxSys 212 which came out in 1996 is no longer supported by Line 6 and can be very difficult if not impossible to repair and yet my '66 Fender Bassman lives on. -

I don't think so. If that were the case loads of us would be blowing cabs all over place. For example, someone running a Trace Elliot Elf into an 8 ohm cab rated at 400w is only using the Elf at its 8 ohm power rating of 130w. There are dozens of players who do that and i doubt any of them have blown their cabs doing so. I'm not a tech guy but my understanding is that the power rating of a cab is the maximum power it can take within its limitations. So running 2000w flat out into a cab rated at 400w probably wouldn't be the best idea in the world, but running an Elf into that same cab would be fine as the Elfs power rating is less than the maximum that the cab can take.

Just had a follow up from my MP who apparently sent my concerns to the Secretary of State. I'm not sure the reply really says anything we didn't already know though. -
The Bugera PCBs won't be involved in my build. I'll be making my own eyelet board - the layout will use some aspects of the original, but modified to accommodate the smoothing capacitors which Fender used to put in a separate 'dog house'.

The TC head will be Class D amp and the Sound City ‘old school’. A different class that someone more knowledgeable than me can explain. Any ‘new’ (class D) amp will need to be several times the wattage of your SCs 120w to produce the same sort of power. There are lots of threads here explaining the ‘details’. For your particular problem I would have thought ‘more watts & turn down’ would be the way to go. But beware that you need to make sure bandmates don’t ’helpfully turn your rig up’ thus blowing a speaker.

Oh hey — Reverb here. 👋 Just to clarify, Reverb is not being purchased by Fender. Two new investors—Creator Partners + Servco—have entered an agreement to purchase Reverb. I think the confusion probably stems from the fact that Servco has a long history with Fender stretching back to the '50s, and is now a majority owner of Fender. Once the deal closes, although we'll share a common investor with Fender, Reverb will be a privately-held, independently operated company. You can read more on our blog. Cheers!
