300 WPC power amp:

Great build! @hydrovac
Coming up nicely...
Thanks.

After preamp builds spree, you seem to have upped the ante with power amp builds. Looking forward to hearing this amp.
Sure capt... also there are other things to listen to, if you manage to find time.


Build in Progress...
Modules in enclosure... tight squeeze, but manageable. with the thick secondary leads, hook up will be a task.
Wired the speaker protection module to begin with.

@hydrovac

Nice clean build. Could you please share the details from where the chasis has been procured.
As I mentioned in the beginning of thread, it's a DIY chassis.


Great going Sir, I am sure its going to be a fine amp. What preamp do you intend to use Sir ? also has the blameless pre passed the stringent "hydrovac" test ? please do let me know
Yes Pranjal... the Blameless is a nice sounding pre. And, as captrajesh posted, after preamp building spree my current collection is around 13 different preamps, (both tube and SS). To me, they all sound good, just a bit different from each other.
I used all kinds of enclosures i could lay my hands on... not all the preamps are DIY though.

The preamps list:

1. SJK (self design based on TI schematic)
2. Discrete Dynamics Class A (Aniket)
3. Peeceebee (shaan)
4. Xiang Sheng 708B (tube)
5. Little Dot mkiv (tube)
6. Pass BA-3 preamp (front end)
7. Blameless class A
8. WAYNE'S BURNING AMP 2018
9. Baxandall tone control
10. ESP project 97
11. Nelson Pass SSP
12. Salcon pre
13. Dynaco PAS 3X (tube)

Wow!
hydrovac, great DIY effort... i have never seen this many preamps in ones possession.
Curious to know the reason... and is it going to stop here or will this continue?
