Yes, a Sony STR-V6 Bluetooth connection needs no soldering. Best path: a Bluetooth receiver with RCA output into the AUX input (150 mV line level, with DIN at the same figure, per the manual transcription). If AUX is taken, use a Tape loop. Rated 115 W/ch into 8 ohms, the STR-V6 documented here is the 1978 V-series receiver the transcription describes, 21.9 kg of it.

Plugging into the STR-V6
AUX input
RecommendedAUX/line and the DIN connection both rate 150 mV per the manual transcription, so a line-level Bluetooth receiver with RCA output finds a home there. The level check earns its minute on a 150 mV input.
Tape monitor loops
Good alternativeRecord outputs split 150 mV on line and 40 mV on DIN along the tape chain. To borrow a loop, attach the Bluetooth unit to its play jacks, call up the tape position on the monitor, and put the monitor back to off for the other sources.
Phono input
Not for line-levelThe MM phono stage is a cartridge input at 2.5 mV. A line-level Bluetooth output would overload the stage, and the turntable would lose its input.
Connecting the STR-V6 in three steps
- AUX holds the adapter
The tape loops are for recorders; AUX is for the wireless feed.
- Wire it and power it
Bluetooth receiver RCA output to AUX, its USB power sorted, and one pairing with your phone.
- Sound up slowly
Volume at the bottom, AUX selected, then raise. Fixed/line output on the adapter is the setting to use if the option exists.
STR-V6 quirks worth knowing
- One documented generation (verified): the transcription dates this V6 to 1978 with the STR-V5 and STR-V7 as listed siblings, and targeted searches for an earlier V-series receiver of the same name returned nothing supportable. This page documents the 1978 set and carries the reference-site absences as part of that record.
- 115 honest watts in 1978 (verified): the transcription's 115 W/ch into 8 ohms at 0.07% distortion, with a resale listing's "2 × 115 WRMS monster receiver" phrasing in agreement, places the V6 in this archive's 110-plus-watt shelf beside the Sansui 9090 and G-8000.
- A 100 dB line figure (verified): the transcription's 100 dB line signal-to-noise is among the best documented in this archive's Sony set, one more datum that arrives because the source is the manual transcription rather than a listing.
Kit for adding Bluetooth to the STR-V6
- Bluetooth receiver with RCA output; LDAC or aptX HD stand first
- RCA cable, 0.5–1 m, for the run
- USB power for the receiver side
FAQ
Plug a Bluetooth receiver with RCA output into the AUX input and select AUX. If AUX is occupied, use a Tape input through the tape monitor. No internal modification is needed.
Per the manual transcription: AUX/line 150 mV, DIN 150 mV, and MM phono 2.5 mV, with signal-to-noise of 100 dB on line and 75 dB on phono. Outputs run 150 mV (line) and 40 mV (DIN), into speakers of 4 to 16 ohms.
The manual transcription rates 115 W per channel into 8 ohms with a frequency response of 5 Hz to 50 kHz at 0.07% distortion and a damping factor of 40. A resale listing quoting 2 × 115 W RMS for a "monster receiver" agrees with that figure.
The documented record here covers a single generation: the 1978 receiver the manual transcription describes, with the STR-V5 and STR-V7 as listed siblings. A used-unit buyer should still confirm features on the set itself, since this site's two reference encyclopedias carry no V6 entry at all.
