Beta Lead Question

[Stephan]

I've been on a quest to find a sunn beta lead head. My searching has led me to an old beta lead combo (2x12). My question is: Are there any differences between the head in the combo vs. the straight up, regular head. Also, if it has no footswitch, is it easy to say, make a new one, or find another that is compatible? What do the combos list for? I hope to use the head to power a cab or two. Thanks for any useful information offered.

Hello:
 Combo heads and stand alone heads are identical.

how about the issue with the footswitch? would any old footswitch do? are the ones that go with the amp as hard to find as i think they are? thanks for your help with my questions.

Hello:
 You can build one. The schematics are on this site. I sold my last NOS pedal last year. Finding one is rare indeed.

well, the combo i found sold today to another person. hopefully the next one that comes around is equipped with the footswitch. if not, i know where to come. cheers!

according to the '79 catalog on this site, the beta lead uses the "beta switch III". i can only seem to find the schematic for the beta switch iv & v on this site. am i blind? i don't mean to sound lazy, but could you point me in the right direction. thanks,

Hello:
 As I remember there was only the 2 pedals. They used the same 4 pin connector. One pedal was for Bass without the reverb switch the other was for the Lead with reverb.
