"Bugle" Phono

[audioDIYer]

I have a BIG problem with Jim's "Bugle" Phono.
Hagerman Technology LLC: Bugle Opamp Moving Magnet Budget Phonostage DIY Kit

I have no bass compared to other RIAA preamps.

Where I must change components to get bass without interferring with RIAA curve?

I'm using Ortophon OM5E cartridge.

Maybe you got some part value in the wrong place? Did you check thoroughly?

 

[Nanook]

er , have you contacted Hagerman?

I'll re-check all components..
The strange thing is I get all bands sounding explendid.. Only bass is lacking.. Not the 'lack' itself but the level..

Did you try lifting the VTA?

Did you try lifting the VTA?

VTA stands for?

VTA= Vertical Tracking Angle, it's not YOUR problem for me...
Looking at the incomplete schematics on their website: check R10, R14, C3, then C1 (.22uf?).
