Mini Portable Guitar Amplifier
This small amplifier was intended to be used in conjunction with an electric guitar to do some low power monitoring, mainly for practice, either via an incorporated small loudspeaker or headphones. The complete circuit, loudspeaker, batteries, input and output jacks...
1W guitar amplifier
An alternative to the well-known ROG Ruby amplifier, this design shares a similar topology, featuring a buffer and a chip amplifier. It employs a JFET buffer utilizing the MPF102, along with the 1W TDA7052 chip. The amplifier delivers a clean...
Mesa Mark IIc+ Preamplifier
The Mark IIc+ amplifier is highly regarded and sought after, with only 1500 units produced in the 1980s, now valued between $4000 and $5000. One notable artist associated with this amplifier is John Petrucci. Due to affordability issues, a simplified...
Odd-ball PI circuit identification request and headroom question
This schematic has been modified from an old Bell & Howell projector amplifier for model 302, utilizing PP 6V6 tubes with a 12AU7 phase inverter (PI). The PI circuit appears to be closest to a "floating paraphase." There is a...
60 Watt Guitar Amplifier
This design utilizes a well-established circuit topology for the power amplifier, employing a single-rail supply of approximately 60V and capacitor coupling for the speakers. The advantages of this configuration for a guitar amplifier include a straightforward circuit design, even at...
60W Guitar Amplifier
This design adopts a well established circuit topology for the power amplifier, using a single-rail supply of about 60V and capacitor-coupling for the speaker(s). The advantages for a guitar amplifier are the very simple circuitry, even for comparatively high power...
