Marantz Model 30 and 32 Amp Drivers

[dbxdx5]

In the Marantz Model 30, they are Motorola parts SJE569 (Q210) and SJE570 (Q209), and in the Model 32, they are S33690 (Q209) and S33691 (Q210). Scant to no information about these drivers exist online or in any of my transistor sub books. The best direction I've been able to find with regard to replacements is in this thread where the poster believes he successfully used MJE3055 and MJE2955 as subs. If anyone else has suggestions, let me know. Thanks.

I used MJE3055 and MJE2955 in a Model 30, and they were fine.
