If it's similar to the tremolo TMB it's really great.. in fact the best you can get imhoJMPGuitars wrote: ↑Sun 05/09/21 7:28 amHave you played a Superlite TMB? The preamp distortion is great. I've used a attenuator with it too, but even that wasn't really necessary.

Re: Build question 18 watt Superlite TMB
They're both great, but not exactly the same. The Tremolo TMB has V1 into parallel V2, and Superlite TMB has the V1 halves cascaded. Both sound good. You gotta build one to really know though. Hahahahaha

It will be the 1W version though.. but it will come to thatJMPGuitars wrote: ↑Sun 05/09/21 8:57 amThey're both great, but not exactly the same.

Re: Build question 18 watt Superlite TMB
Hello,
which PT will be suitable 290PAZ OR 290CAX. is the 630V too much for Superlite TMB? cax is 50 CDN less.
Thank you

Re: Build question 18 watt Superlite TMB
Yeah. And I built a 2W submini version of the Superlite too, as well as the standard TMB preamp in one of my test chassis. Each to their own, although I am a self confessed overdriven power pentode addict. TMB preamp distortion is a flavour to blend into the essential power stage distortion for me. But I can certainly respect other options.JMPGuitars wrote: ↑Sun 05/09/21 7:28 amHave you played a Superlite TMB? The preamp distortion is great.

Re: Build question 18 watt Superlite TMB
I hear that. Power tube distortion is the best, but in the Superlite TMB, I think the preamp distortion is also quite good. Of course the guitar and speaker effect the final outcome too.katopan wrote: ↑Wed 05/12/21 6:43 amYeah.

Re: Build question 18 watt Superlite TMB
Preamp distortion in my 2104-based 36W is also excellent. Very smooth and lots of sustain. I attenuate the signal before the PI so only the preamp breaks up. It's a very familiar sound, reminds me a great deal of early Hendrix.JMPGuitars wrote: ↑Wed 05/12/21 7:15 amI hear that.

Re: Build question 18 watt Superlite TMB
Thanks Katopan, I intentionally designed that preamp to give good, thick distortion.katopan wrote: ↑Wed 05/12/21 6:43 amJMPGuitars wrote: ↑Sun 05/09/21 7:28 amHave you played a Superlite TMB? The preamp distortion is great. I've used a attenuator with it too, but even that wasn't really necessary.

Re: Build question 18 watt Superlite TMB
I have sourced most of the parts for this build. and getting excited to start the build. The PT is a hammond 290PAZ with 580VCT. What B+ voltage am I expecting please explain if possible. will I get 290-0-290 with this PT.
what does the 2.2K 5watt resistor do that connects the two 32uf of the can cap and how different value will affect the voltage on the plates of EL84? i forgot to order this resistor.
thanks

Re: Build question 18 watt Superlite TMB
580VCT (Volts Center-Tapped) is the same thing as 290-0-290. 290+290=580, and the 0 is the CT.mehfuzhoss wrote: ↑Thu 05/20/21 1:29 pmI have sourced most of the parts for this build. and getting excited to start the build.

The 2.2K 5W resistor drops the voltage and isolates (along with the filter caps) the first and second B+ nodes. This resistor is essential, however, you can run any value between 1.5K to 2.2K as long as it's 5W. You will simply need to test your voltages and make sure the power tube screens are below the plate voltages. I recommend 1K 3W screen resistors.
Thanks,
Josh
