The Chrome, Cute Preamps Are Challenging to Sound Right...

While I treasure these preamp icons, they do require some hard work to get right. They have little room inside; especially with the tight innards of the stereo units. Their potential is VERY REWARDING SONICALLY; even if simply upgrading the power supply, tweaking the Active Phono EQ and correcting the input resistance.

Having upgraded more than a few of these, I must warn you that every unit's original final coupling caps leaked DC voltage at the output. Connected to an amp with no input cap in the amp can quickly sound harsh, as leaking DC changes the bias of the next stage. The resulting sound can get fuzzy quickly. Rather than decipher one system installment, as other posters have already, perhaps it is the right time for me to start a new thread about these cute, chrome preamps; which I will post above...Best Regards & ENJOY !
