Hi guys,
I am planning to build my first tube amp, either a hi-fi stereo amp or a mono guitar/bass amp.
Right now I am trying to decide which circuit to build based on the simplicity and parts availability, but one issue I am facing is the availability of the correct specification transformers for a reasonable price, as I have to build the amp on a tight budget.
Having checked the prices online, I found that although tubes and rest of the components are moderately priced, the transformers are costing around 5-6K for power transformers and over 10K for the output transformers. For example this Hammond model which is suggested for the guitar amp circuit is over 10K + shipping.
Hoping that you guys can suggest some more economical options, like any local sources for suitable used transformers, or if I can get them custom-made to the required specs?
I have also considered attempting to DIY the transformers using the formulas for calculating the windings, but could not find much information on what type of laminations, etc to use and where to source them...
My budget for the project is max around 25-30K, so would appreciate any suggestions on what will be a suitable circuit to build from an Indian standpoint in regards to parts availability ...
So far I am considering:
1. AX84 Project - with some modifications to use with bass guitar
2. This single ended KT88 circuit for stereo hi-fi amp by Blueglow Electronics on YouTube
3. Mullard 3-3 or 5-10
